TUMPL02	Streamlining Support and Development Activities Across the Distinct Support Groups of the ALBA Synchrotron with the Implementation of a New Service Management System	298
	M. Martin, A. Burgos, C. Colldelram, G. Cuní, D. Fernández-Carreiras, E. Fraga, G. García López, O. Matilla, A. Pérez Font, D. Salvat ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	The MIS section in the Computing division at ALBA Synchrotron designs and supports management information systems. This paper describes the streamlining of the work of 12 support groups into a single customer portal and issue management system. Prior to the change, ALBA was using five different ticket systems. To improve coordination, we searched tools able to support ITIL Service Management, as well as PRINCE2 and Agile Project Management. Within market solutions, JIRA, with its agile boards, calendars, SLAs and service desks, was the only solution with a seamless integration of both. Support teams took the opportunity to redesign their service portfolio and management processes. Through the UX design, JIRA has proved to be a flexible solution to customize forms, workflows, permissions and notifications on the fly, creating a virtuous cycle of rapid improvements, a rewarding co-design experience which results in highly fitting solutions and fast adoption. Team, project and service managers now use a single system to track requests in a timely manner, view trends, and get a consolidated view of efforts invested in the different beamlines and accelerators.

TUPHA001	Research on Fault Diagnosis of Power Supply Control System on BEPCII	361
	D. Wang, J. Liu, X.L. Wang IHEP, Beijing, People's Republic of China
	The reliable and stable operation of the accelerator is the premise and foundation of physics experiments. For example, in the BEPCII, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment's cycle costing. The multi-signal flow model proposed by Pattipati K.R is considered as the preferred method of industrial equipment faults detection. However, there are still some problems about fault probability conflict in the processing of correlation matrix diagnosis due to the hierarchical nature of multi-signal flow modeling. Thus we develop the fault diagnosis strategy based on the important prior knowledge of the fault. This method is applied to the front-end electronic devices of BEPCII magnet power supply control system and improves the fault diagnosis and analysis ability of magnet power supply control system.

	With many synchrotron facilities retiring or going through upgrades, what is the future of the some of the state-of-the-art equipment and the beamlines built for a specific science at these older facilities? Can the past investments continue supporting the current scientific mission? Beamlines Developed by NSLS2 (BDN) started in 2013 as the NxtGen project prior to NSLS last light on September, 30 2014. Hundreds of pieces of equipment still scientifically useful and valuable have been collected, packed and stored to become part of the new beamlines at the NSLS2 complex. CMS and TES beamlines were built in 2016 in 6 month from bare hutches to the First Light and are already doing user science. QAS, XFM, FIS/MET are taking first light in late 2017/early 2018 and users in 2018. Repurposed components have been fitted with standard NSLS2 EPICS based control systems, Delta Tau motion controllers, digital imaging. Intensity monitors and diagnostics have been equipped with new electronics. Data collection is performed via home grown customizable, beamline specific Bluesky Data Acquisition System. Status of the project and an overview of controls efforts will be presented.

	Funding: This work is supported by the Italian Ministry of Education, University, and Research (MIUR) with funds specifically assigned to the Italian National Institute of Astrophysics (INAF) The Cherenkov Telescope Array (CTA) project is an international initiative to build a next generation ground-based observatory for very high energy gamma-rays. Three classes of telescopes with different mirror size will be located in the northern and southern hemispheres. The ASTRI mini-array of CTA preproduction is one of the small sized telescopes mini-arrays proposed to be installed at the CTA southern site. The ASTRI mini-array will consist of nine units based on the end-to-end ASTRI SST-2M prototype already installed on Mt. Etna (Italy). The mini-array software system (MASS) supports the end to end ASTRI SST-2M prototype and miniarray operations. The ASTRI software integration team defined the procedures to perform effectively the integration test and release activities. The developer has to properly use the repository tree and branches according to the development status. We require that the software includes also specific sections for automated tests and that the software is well tested (in simulated and real system) before any release. Here we present the method adopted to release the first MASS version to support the ASTRI SST-2M prototype test and operation activities. * conforti@iasfbo.inaf.it

TUPHA006	Automation of the Software Production Process for Multiple Cryogenic Control Applications	375
	C.F. Fluder, V. Lefebvre, M. Pezzetti, A. Tovar González CERN, Geneva, Switzerland P. Plutecki AGH University of Science and Technology, Kraków, Poland T. Wolak AGH, Cracow, Poland
	The development of process control systems for the cryogenic infrastructure at CERN is based on an automatic software generation approach. The overall complexity of the systems, their frequent evolution as well as the extensive use of databases, repositories, commercial engineering software and CERN frameworks led to further efforts towards improving the existing automation based software production methodology. A large number of control system upgrades were successfully performed for the Cryogenics in the LHC accelerator, applying the Continuous Integration practice integrating all software production tasks, tools and technologies. The production and maintenance of the control software for multiple cryogenic applications became more reliable while significantly reducing the required time and effort. This concept became a guideline for development of process control software for new cryogenic systems at CERN. This publication presents the software production methodology, as well as the summary of several years of experience with the enhanced automated control software production, already implemented for the Cryogenics of the LHC accelerator and the CERN cryogenic test facilities.

	Funding: The Swedish Research Council (VetenskapsrÃ¥det MAX IV / SOLEIL collaboration) The Ile de France region (project <FORTE>, DIM-Oxymore) Two years ago, SOLEIL (France) and MAXIV(Sweden) synchrotron light sources started a joint project to partially fund two similar in-vacuum diffractometers to be installed at the tender X-ray beamlines SIRIUS and FemtoMAX . SOLEIL diffractometer, manufactured by the French company SYMETRIE* and complementarily funded by a <Ile de France> region project (DIM Oxymore) gathering SIRIUS beamline and other laboratories, features an in-vacuum 4-circles goniometer and two hexapods. The first hexapod is used for the alignment of the vacuum vessel, and the second one for the alignment of the sample stage which is mounted on the 4-circles diffractometer. In order to integrate efficiently this complex mechanical experimental station into SOLEIL control architecture based on TANGO and DeltaTau motion controller, SOLEIL and SYMETRIE work in a close collaboration. Synchronization of the different elements of the diffractometer is a key issue in this work to get a good sphere of confusion thanks to corrections done by the in vacuum hexapod. This paper details this collaboration, status of the project in terms of control system capabilities and the results of the first tests. *SYMETRIE Company (Hexapod and positioning systems) http://www.symetrie.fr/

TUPHA008	Software Quality Assurance for the Daniel K. Inouye Solar Telescope Control Software	385
	A. Greer, A. Yoshimura OSL, Cambridge, United Kingdom B.D. Goodrich, S. Guzzo, C.J. Mayer Advanced Technology Solar Telescope, National Solar Observatory, Tucson, USA
	The Daniel K. Inouye Solar Telescope (DKIST) is currently under construction in Hawaii. The telescope control system comprises a significant number of subsystems to coordinate the operation of the telescope and its instruments. Integrating delivered subsystems into the control framework and managing existing subsystem versions requires careful management, including processes that provide confidence in the current operational state of the whole control system. Continuous software Quality Assurance provides test metrics on these systems using a Testing Automation Framework (TAF), which provides system and assembly test capabilities to ensure that software and control requirements are met. This paper discusses the requirements for a Quality Assurance program and the implementation of the TAF to execute it.

THCPL01	Speaking of Diversity	1168
	K.S. White ORNL, Oak Ridge, Tennessee, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725. Historically, attendance at the International Conference on Accelerator and Large Experimental Physics Control Systems has not been particularly diverse in terms of gender or race. In fact, the lack of diversity amongst the attendees was noted during the closing session of the 2015 conference by an invited speaker from outside the accelerator community. Informal discussion and observations support the assertion that our conference attendance reflects the diversity of the broader accelerator controls workforce. Facing very low participation of women in our field and even lower minority representation, it is important to examine this issue as studies point to the importance of diverse work groups to spark innovation and creativity as catalysts to solving difficult problems. This paper will discuss diversity and inclusion in the disciplines that comprise the accelerator controls workforce, including background, barriers and strategies for improvement.

	M. Pecchioli ESA/ESOC, Darmstadt, Germany J.M. Carranza ESA-ESTEC, Noordwijk, The Netherlands
	Funding: European Space Agency The European Ground System Common Core (EGS-CC) initiative is now materializing. The goal of the this initiative is to define, build and share a software framework and implementation that will be used as the main basis for pre- and post- launch ground systems (Electrical Ground Support Equipment and Mission Control System) of future European space projects. The initiative is in place since year 2011 and is being led by the European Space Agency as a formal collaboration of the main European stakeholders in the space systems control domain, including European Space National Agencies and European Prime Industry. The main expected output of the EGS-CC initiative is a core system which can be adapted and extended to support the execution of pre- and post-launch Monitoring and Control operations for all types of missions and throughout the complete life-cycle of space projects. This presentation will introduce the main highlights of the EGS-CC initiative, its governance principles, the fundamental concepts of the resulting products and the challenges that the team is facing.

THCPL03	A Success-History Based Learning Procedure to Optimize Server Throughput in Large Distributed Control Systems	1182
	Y. Gao, T.G. Robertazzi Stony Brook University, Stony Brook, New York, USA K.A. Brown BNL, Upton, Long Island, New York, USA J. Chen Stony Brook University, Computer Science Department, Stony Brook, New York, USA
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-SC0012704 with the U.S. Department of Energy. Large distributed control systems typically can be modeled by a hierarchical structure with two physical layers: Console Level Computers (CLCs) and Front End Computers (FECs). The controls system of the Relativistic Heavy Ion Collider (RHIC) consists of more than 500 FECs, each acting as a server providing services to a potentially unlimited number of clients. This can lead to a bottleneck in the system. Heavy traffic can slow down or even crash a system, making it momentarily unresponsive. One mechanism to circumvent this is to transfer the heavy communications traffic to more robust higher performance servers, keeping the load on the FEC low. In this work, we study this client-server problem from a different perspective. We introduce a novel game theory model for the problem, and formulate it into an integer programming problem. We point out its difficulty and propose a heuristic algorithms to solve it. Simulation results show that our proposed schemes efficiently manage the client-server activities, and result in a high server throughput and a low crash probability.

	Funding: U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules and 500-terawatts of ultraviolet light to a target. Officially commissioned as an operational facility on March 21, 2009, NIF is expected to conduct research experiments thru 2039. The 30-year lifespan of the control system presents several challenges in meeting reliability, availability, and maintainability (RAM) expectations. As NIF continues to expand on its experimental capabilities, the control system's software base of 3.5 million lines of code grows with most of the legacy software still in operational use. Supporting this software is further complicated by technology life cycles and turnover of senior experienced staff. This talk will present lessons learned and new initiatives related to technology refreshes, risk mitigation, and changes to our software development and test methodology to ensure high control system availability for supporting experiments throughout NIF's lifetime.

THMPL01	A Simple Temporal Network for Coordination of Emergent Knowledge Processes in a Collaborative System-of-Systems	1252
	M.A. Schaffner Sandia National Laboratories, Albuquerque, New Mexico, USA
	Funding: U.S. Department of Energy's National Nuclear Security Administration, DE-NA0003525 The Z Machine is the world's largest pulsed power machine, routinely delivering over 20 MA of electrical current to targets in support of US nuclear stockpile stewardship and in pursuit of inertial confinement fusion. The large-scale, multi-disciplinary nature of experiments ('shots') on the Z Machine requires resources and expertise from disparate organizations with independent functions and management, forming a Collaborative System-of-Systems. This structure, combined with the Emergent Knowledge Processes central to preparation and execution, creates significant challenges in planning and coordinating required activities leading up to a given experiment. The present work demonstrates an approach to scheduling planned activities on shot day to aid in coordinating workers among these different groups, using minimal information about activities' temporal relationships to form a Simple Temporal Network (STN). Historical data is mined, allowing a standard STN to be created for common activities, with the lower bounds between those activities defined. Activities are then scheduled at their earliest possible times to provide participants a time to check-in when interested. maschaf@sandia.gov

	KEK injector linac has delivered electrons and positrons for particle physics and photon science experiments for more than 30 years. It is being upgraded for the SuperKEKB project, which aims at a 40-fold increase in luminosity over the previous project of KEKB, in order to increase our understanding of flavour physics. This project requires ten-times smaller emittance and five-times larger current in injection beam from the injector. And many hardware components are being tested and installed. Even during the 6-year upgrade, it was requested to inject beams into light sources storage rings of PF and PF-AR. Furthermore, the beam demanding approaches from those storage rings are different. SuperKEKB would demand highest performance, and unscheduled interruption may be acceptable if the performance would be improved. However, light sources expect a stable operation without any unscheduled break, mainly because most users run experiments for a short period. In order to deal with the both requirements several measures are taken for operation, construction and maintenance strategy including simultaneous top-up injections.

THPHA002	SLAC LCLS-II Injector Source Controls and Early Injector Commissioning	1340
	D. Rogind, M. Boyes, H. Shoaee SLAC, Menlo Park, California, USA
	LCLS-II is a superconducting upgrade to the existing Linear Coherent Light Source at SLAC with a continuous wave beam rate of up to 1 MHz. Construction is underway with first light planned for 2020. The LCLS-II Injector section that comprises low energy from the gun up to the location of the first cryomodule is based on the LBNL Advanced Photo-Injector Experiment (APEX), and is being provided by LBNL. In 2015, responsibility for controls design and fabrication was transferred to SLAC from LBNL to promote commonality with the rest of the LCLS-II control subsystems. Collaboration between the LBNL APEX controls community and SLAC LCSL-II controls team proved vital in advancing the controls architecture toward standardized implementations integrated with the rest of LCLS-II. An added challenge was a decision to commission the injector ~1.5 years ahead of the rest of the machine, in FY 2018. This early injector commissioning (EIC) is embraced as an opportunity to gain valuable experience with the majority of the LCLS-II controls, especially the 1MHz high performance subsystems (HPS), prior to first light.

THPHA003	Installation and the Hardware Commissioning of the European XFEL Undulator Systems	1344
	M. Yakopov, S. Abeghyan, S. Karabekyan, J. Pflüger XFEL. EU, Schenefeld, Germany
	This article describes in detail the steps of hardware installation and commissioning of components for undulator systems at European XFEL. In general, the work can be divided into 3 different steps: installation, alignment, and commissioning. During installation step, the following main components were rolled into the tunnel: - undulators with the control cabinets, intersection control cabinets, phase shifters, quadrupole movers, correction coils. They have been mounted according to the designed positions. Then all mentioned components have been aligned according to the specifications. Finally, the cabling has been done and basic tests were performed. As part of the commissioning, the calibration of the temperature sensors, as well as the measurements of the quadrupole mover travel distance has been done in the tunnel. Afterwards, the undulator limit switches and hard stops were adjusted to secure the vacuum chamber by closing the undulator gap up to 10mm. Eventually, the system was handed over to the global control system in order to perform all functional tests. The main focus is given to the components which are controlled or monitored by the undulator local control system [1].

	Industrial power supplies deliver high and low voltage to a wide range of CERN's detector and accelerator components. These power supplies, sourced from external companies, are integrated into control systems via industry standard OPC servers. The servers are now being modernized. A key lesson learnt from running the previous generation of OPC servers is that vendor specific, black-box implementations can be costly in terms of support effort, particularly in diagnosing problems in large production-site deployments. This paper presents the projects producing the next generation of OPC servers; following an open, collaborative approach and a high degree of homogenization across the independent partners. The goal is to streamline development and support costs via code re-use and a template architecture. The collaborations aim to optimally combine CERN's OPC and production operations knowledge with each company's experience in integrating their hardware. This paper describes the considerations and constraints taken into account, including legal aspects, product commercialization and technical requirements to define a common collaborative approach across three hardware manufacturers.

The MIS section in the Computing division at ALBA Synchrotron designs and supports management information systems. This paper describes the streamlining of the work of 12 support groups into a single customer portal and issue management system. Prior to the change, ALBA was using five different ticket systems. To improve coordination, we searched tools able to support ITIL Service Management, as well as PRINCE2 and Agile Project Management. Within market solutions, JIRA, with its agile boards, calendars, SLAs and service desks, was the only solution with a seamless integration of both. Support teams took the opportunity to redesign their service portfolio and management processes. Through the UX design, JIRA has proved to be a flexible solution to customize forms, workflows, permissions and notifications on the fly, creating a virtuous cycle of rapid improvements, a rewarding co-design experience which results in highly fitting solutions and fast adoption. Team, project and service managers now use a single system to track requests in a timely manner, view trends, and get a consolidated view of efforts invested in the different beamlines and accelerators.

Research on Fault Diagnosis of Power Supply Control System on BEPCII

361

IHEP, Beijing, People's Republic of China

The reliable and stable operation of the accelerator is the premise and foundation of physics experiments. For example, in the BEPCII, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment's cycle costing. The multi-signal flow model proposed by Pattipati K.R is considered as the preferred method of industrial equipment faults detection. However, there are still some problems about fault probability conflict in the processing of correlation matrix diagnosis due to the hierarchical nature of multi-signal flow modeling. Thus we develop the fault diagnosis strategy based on the important prior knowledge of the fault. This method is applied to the front-end electronic devices of BEPCII magnet power supply control system and improves the fault diagnosis and analysis ability of magnet power supply control system.

With many synchrotron facilities retiring or going through upgrades, what is the future of the some of the state-of-the-art equipment and the beamlines built for a specific science at these older facilities? Can the past investments continue supporting the current scientific mission? Beamlines Developed by NSLS2 (BDN) started in 2013 as the NxtGen project prior to NSLS last light on September, 30 2014. Hundreds of pieces of equipment still scientifically useful and valuable have been collected, packed and stored to become part of the new beamlines at the NSLS2 complex. CMS and TES beamlines were built in 2016 in 6 month from bare hutches to the First Light and are already doing user science. QAS, XFM, FIS/MET are taking first light in late 2017/early 2018 and users in 2018. Repurposed components have been fitted with standard NSLS2 EPICS based control systems, Delta Tau motion controllers, digital imaging. Intensity monitors and diagnostics have been equipped with new electronics. Data collection is performed via home grown customizable, beamline specific Bluesky Data Acquisition System. Status of the project and an overview of controls efforts will be presented.

The Cherenkov Telescope Array (CTA) project is an international initiative to build a next generation ground-based observatory for very high energy gamma-rays. Three classes of telescopes with different mirror size will be located in the northern and southern hemispheres. The ASTRI mini-array of CTA preproduction is one of the small sized telescopes mini-arrays proposed to be installed at the CTA southern site. The ASTRI mini-array will consist of nine units based on the end-to-end ASTRI SST-2M prototype already installed on Mt. Etna (Italy). The mini-array software system (MASS) supports the end to end ASTRI SST-2M prototype and miniarray operations. The ASTRI software integration team defined the procedures to perform effectively the integration test and release activities. The developer has to properly use the repository tree and branches according to the development status. We require that the software includes also specific sections for automated tests and that the software is well tested (in simulated and real system) before any release. Here we present the method adopted to release the first MASS version to support the ASTRI SST-2M prototype test and operation activities.

The development of process control systems for the cryogenic infrastructure at CERN is based on an automatic software generation approach. The overall complexity of the systems, their frequent evolution as well as the extensive use of databases, repositories, commercial engineering software and CERN frameworks led to further efforts towards improving the existing automation based software production methodology. A large number of control system upgrades were successfully performed for the Cryogenics in the LHC accelerator, applying the Continuous Integration practice integrating all software production tasks, tools and technologies. The production and maintenance of the control software for multiple cryogenic applications became more reliable while significantly reducing the required time and effort. This concept became a guideline for development of process control software for new cryogenic systems at CERN. This publication presents the software production methodology, as well as the summary of several years of experience with the enhanced automated control software production, already implemented for the Cryogenics of the LHC accelerator and the CERN cryogenic test facilities.

Two years ago, SOLEIL (France) and MAXIV(Sweden) synchrotron light sources started a joint project to partially fund two similar in-vacuum diffractometers to be installed at the tender X-ray beamlines SIRIUS and FemtoMAX . SOLEIL diffractometer, manufactured by the French company SYMETRIE* and complementarily funded by a <Ile de France> region project (DIM Oxymore) gathering SIRIUS beamline and other laboratories, features an in-vacuum 4-circles goniometer and two hexapods. The first hexapod is used for the alignment of the vacuum vessel, and the second one for the alignment of the sample stage which is mounted on the 4-circles diffractometer. In order to integrate efficiently this complex mechanical experimental station into SOLEIL control architecture based on TANGO and DeltaTau motion controller, SOLEIL and SYMETRIE work in a close collaboration. Synchronization of the different elements of the diffractometer is a key issue in this work to get a good sphere of confusion thanks to corrections done by the in vacuum hexapod. This paper details this collaboration, status of the project in terms of control system capabilities and the results of the first tests.

The Daniel K. Inouye Solar Telescope (DKIST) is currently under construction in Hawaii. The telescope control system comprises a significant number of subsystems to coordinate the operation of the telescope and its instruments. Integrating delivered subsystems into the control framework and managing existing subsystem versions requires careful management, including processes that provide confidence in the current operational state of the whole control system. Continuous software Quality Assurance provides test metrics on these systems using a Testing Automation Framework (TAF), which provides system and assembly test capabilities to ensure that software and control requirements are met. This paper discusses the requirements for a Quality Assurance program and the implementation of the TAF to execute it.

Historically, attendance at the International Conference on Accelerator and Large Experimental Physics Control Systems has not been particularly diverse in terms of gender or race. In fact, the lack of diversity amongst the attendees was noted during the closing session of the 2015 conference by an invited speaker from outside the accelerator community. Informal discussion and observations support the assertion that our conference attendance reflects the diversity of the broader accelerator controls workforce. Facing very low participation of women in our field and even lower minority representation, it is important to examine this issue as studies point to the importance of diverse work groups to spark innovation and creativity as catalysts to solving difficult problems. This paper will discuss diversity and inclusion in the disciplines that comprise the accelerator controls workforce, including background, barriers and strategies for improvement.

Large distributed control systems typically can be modeled by a hierarchical structure with two physical layers: Console Level Computers (CLCs) and Front End Computers (FECs). The controls system of the Relativistic Heavy Ion Collider (RHIC) consists of more than 500 FECs, each acting as a server providing services to a potentially unlimited number of clients. This can lead to a bottleneck in the system. Heavy traffic can slow down or even crash a system, making it momentarily unresponsive. One mechanism to circumvent this is to transfer the heavy communications traffic to more robust higher performance servers, keeping the load on the FEC low. In this work, we study this client-server problem from a different perspective. We introduce a novel game theory model for the problem, and formulate it into an integer programming problem. We point out its difficulty and propose a heuristic algorithms to solve it. Simulation results show that our proposed schemes efficiently manage the client-server activities, and result in a high server throughput and a low crash probability.

The National Ignition Facility (NIF) is the world's largest and most energetic laser experimental facility with 192 beams capable of delivering 1.8 megajoules and 500-terawatts of ultraviolet light to a target. Officially commissioned as an operational facility on March 21, 2009, NIF is expected to conduct research experiments thru 2039. The 30-year lifespan of the control system presents several challenges in meeting reliability, availability, and maintainability (RAM) expectations. As NIF continues to expand on its experimental capabilities, the control system's software base of 3.5 million lines of code grows with most of the legacy software still in operational use. Supporting this software is further complicated by technology life cycles and turnover of senior experienced staff. This talk will present lessons learned and new initiatives related to technology refreshes, risk mitigation, and changes to our software development and test methodology to ensure high control system availability for supporting experiments throughout NIF's lifetime.

A Simple Temporal Network for Coordination of Emergent Knowledge Processes in a Collaborative System-of-Systems

1252

Funding: U.S. Department of Energy's National Nuclear Security Administration, DE-NA0003525
The Z Machine is the world's largest pulsed power machine, routinely delivering over 20 MA of electrical current to targets in support of US nuclear stockpile stewardship and in pursuit of inertial confinement fusion. The large-scale, multi-disciplinary nature of experiments ('shots') on the Z Machine requires resources and expertise from disparate organizations with independent functions and management, forming a Collaborative System-of-Systems. This structure, combined with the Emergent Knowledge Processes central to preparation and execution, creates significant challenges in planning and coordinating required activities leading up to a given experiment. The present work demonstrates an approach to scheduling planned activities on shot day to aid in coordinating workers among these different groups, using minimal information about activities' temporal relationships to form a Simple Temporal Network (STN). Historical data is mined, allowing a standard STN to be created for common activities, with the lower bounds between those activities defined. Activities are then scheduled at their earliest possible times to provide participants a time to check-in when interested.

KEK injector linac has delivered electrons and positrons for particle physics and photon science experiments for more than 30 years. It is being upgraded for the SuperKEKB project, which aims at a 40-fold increase in luminosity over the previous project of KEKB, in order to increase our understanding of flavour physics. This project requires ten-times smaller emittance and five-times larger current in injection beam from the injector. And many hardware components are being tested and installed. Even during the 6-year upgrade, it was requested to inject beams into light sources storage rings of PF and PF-AR. Furthermore, the beam demanding approaches from those storage rings are different. SuperKEKB would demand highest performance, and unscheduled interruption may be acceptable if the performance would be improved. However, light sources expect a stable operation without any unscheduled break, mainly because most users run experiments for a short period. In order to deal with the both requirements several measures are taken for operation, construction and maintenance strategy including simultaneous top-up injections.

SLAC LCLS-II Injector Source Controls and Early Injector Commissioning

1340

SLAC, Menlo Park, California, USA

LCLS-II is a superconducting upgrade to the existing Linear Coherent Light Source at SLAC with a continuous wave beam rate of up to 1 MHz. Construction is underway with first light planned for 2020. The LCLS-II Injector section that comprises low energy from the gun up to the location of the first cryomodule is based on the LBNL Advanced Photo-Injector Experiment (APEX), and is being provided by LBNL. In 2015, responsibility for controls design and fabrication was transferred to SLAC from LBNL to promote commonality with the rest of the LCLS-II control subsystems. Collaboration between the LBNL APEX controls community and SLAC LCSL-II controls team proved vital in advancing the controls architecture toward standardized implementations integrated with the rest of LCLS-II. An added challenge was a decision to commission the injector ~1.5 years ahead of the rest of the machine, in FY 2018. This early injector commissioning (EIC) is embraced as an opportunity to gain valuable experience with the majority of the LCLS-II controls, especially the 1MHz high performance subsystems (HPS), prior to first light.

This article describes in detail the steps of hardware installation and commissioning of components for undulator systems at European XFEL. In general, the work can be divided into 3 different steps: installation, alignment, and commissioning. During installation step, the following main components were rolled into the tunnel: - undulators with the control cabinets, intersection control cabinets, phase shifters, quadrupole movers, correction coils. They have been mounted according to the designed positions. Then all mentioned components have been aligned according to the specifications. Finally, the cabling has been done and basic tests were performed. As part of the commissioning, the calibration of the temperature sensors, as well as the measurements of the quadrupole mover travel distance has been done in the tunnel. Afterwards, the undulator limit switches and hard stops were adjusted to secure the vacuum chamber by closing the undulator gap up to 10mm. Eventually, the system was handed over to the global control system in order to perform all functional tests. The main focus is given to the components which are controlled or monitored by the undulator local control system [1].

The FRIB, is a new heavy ion accelerator facility currently under construction at Michigan State University. It is being built to provide intense beams of rare isotopes. The low level controls system integrates a wide variety of hardware into an EPICS/PLC based control system. This paper will present the challenges encountered with resulting hardware interfaces, and lessons learned that can be applied to future projects. These challenges include both technical design and project management challenges that are encountered when integrating hardware from other departments.

Industrial power supplies deliver high and low voltage to a wide range of CERN's detector and accelerator components. These power supplies, sourced from external companies, are integrated into control systems via industry standard OPC servers. The servers are now being modernized. A key lesson learnt from running the previous generation of OPC servers is that vendor specific, black-box implementations can be costly in terms of support effort, particularly in diagnosing problems in large production-site deployments. This paper presents the projects producing the next generation of OPC servers; following an open, collaborative approach and a high degree of homogenization across the independent partners. The goal is to streamline development and support costs via code re-use and a template architecture. The collaborations aim to optimally combine CERN's OPC and production operations knowledge with each company's experience in integrating their hardware. This paper describes the considerations and constraints taken into account, including legal aspects, product commercialization and technical requirements to define a common collaborative approach across three hardware manufacturers.
