	The Linac Coherent Light Source (LCLS) is a free electron laser (FEL) facility operating at the SLAC National Accelerator Laboratory (SLAC). A stripline beam position monitor (BPM) system was developed at SLAC [1] to meet the performance requirements necessary to provide high-quality stable beams for LCLS. This design has been modified to achieve improved position resolution in a more compact form factor. Prototype installations of this system have been operating in the LCLS LINAC and tested at the Pohang Accelerator Laboratory (PAL). Production systems are deployed at the new PAL XFEL facility and at the SPEAR storage ring at the Stanford Synchrotron Radiation Lightsource at SLAC. This paper presents the design and commissioning results of this system.

MOPGF056	Synchronising High-Speed Triggered Image and Meta Data Acquisition for Beamlines	EPICS, hardware, controls, framework	225
	N. De Maio, A.P. Bark, T.M. Cobb, J.A. Thompson DLS, Oxfordshire, United Kingdom
	High-speed image acquisition is becoming more and more common on beamlines. As experiments increase in complexity, the need to record parameters related to the environment at the same time increases with them. As a result, conventional systems for combining experimental meta data and images often struggle to deliver at a speed and precision that would be desirable for the experiment. We describe an integrated solution that addresses those needs, overcoming the performance limitations of PV monitoring by combining hardware triggering of an ADC card, coordination of signals in a Zebra box* and three instances of area-Detector streaming to HDF5 data. This solution is expected to be appropriate for frame rates ranging from 30Hz to 1000Hz, with the limiting factor being the maximum speed of the camera. Conceptually, the individual data streams are arranged in pipelines controlled by a master Zebra box, expecting start/stop signals on one end and producing the data collections at the other. This design ensures efficiency on the acquisition side while allowing easy interaction with higher-level applications on the other. *T. Cobb, Y. Chernousko, I.

MOPGF088	Integrating the Measuring System of Vibration and Beam Position Monitor to Study the Beam Stability	controls, monitoring, vacuum, network	277
	C. H. Huang, Y.-S. Cheng, P.C. Chiu, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	For a low emittance light source, beam orbit motion needs to be controlled within submicron for obtaining a high quality light. Magnets vibration especially quadruples will be one of the main sources to destroy the beam stability. In order to study the relationship between vibration and beam motion, it is highly desirable to use a synchronous data acquisition system which integrates measurement of vibration and beam position monitor systems especially for the coherence analysis. For a larger vibration such as earthquakes are also deleterious to beam stability or even make the beam trip due to the quench of superconducting RF cavity. A data acquisition system integrated with an earthquake detector is also quite necessary to show and archive the data on the control system. The data acquisition systems of vibration and earthquake measurement system are summarized in this report. The relationship between the beam motion and magnets vibration will also study here.

TUB3O02	Iterative Development of the Generic Continuous Scans in Sardana	controls, experiment, software, hardware	524
	Z. Reszela, G. Cuní, C.M. Falcón Torres, D. Fernández-Carreiras, C. Pascual-Izarra, M. Rosanes Siscart ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	Sardana* is a software suite for Supervision, Control and Data Acquisition in scientific installations. It aims to reduce cost and time of design, development and support of the control and data acquisition systems. Sardana is used in several synchrotrons where continuous scans are the desired way of executing experiments. Most experiments require an extensive and coordinated control of many aspects like positioning, data acquisition, synchronization and storage. Many successful ad-hoc solutions have already been developed, however they lack generalization and are hard to maintain or reuse. Sardana, thanks to the Taurus* based applications, allows the users to configure and control the scan experiments. The MacroServer, a flexible python based sequencer, provides parametrizable turn-key scan procedures. Thanks to the Device Pool controllers interfaces, heterogeneous hardware can be easily plug into Sardana and their elements used during scans and data acquisitions. Development of the continuous scans is an ongoing iterative process and its current status is described in this paper. * http://sardana-controls.org D.

The Disruptor library provides an innovative single-threaded approach, which combines high performance event processing with a simplified software design, implementation and maintenance. This open-source library was originally developed by a financial company to build a low latency trading exchange. In 2014 the high-level control system for CERN experimental areas (CESAR) was renovated. CESAR calculates the states of thousands of devices by processing more than 2500 asynchronous event streams. The Disruptor was used as an event-processing engine. This allowed the code to be greatly simplified by removing the concurrency concerns. This paper discusses the benefits of the programming model encouraged by the Disruptor (simplification of the code base, performance, determinism), the design challenges faced while integrating the Disruptor into CESAR as well as the limitations it implies on the architecture.

WED3O03	MADOCA II Data Logging System Using NoSQL Database for SPRING-8	database, controls, embedded, operation	648
	A. Yamashita, M. Kago JASRI/SPring-8, Hyogo-ken, Japan
	The data logging system for SPring-8 was upgraded to the new system using NoSQL database, as a part of a MADOCA II framework. It has been collecting all the log data required for accelerator control without any trouble since the upgrade. In the past, the system powered by a relational database management system (RDBMS) had been operating since 1997. It had grown with the development of accelerators. However, the system with RDBMS became difficult to handle new requirements like variable length data storage, data mining from large volume data and fast data acquisition. New software technologies gave solution for the problems. In the new system, we adopted two NoSQL databases, Apache Cassandra and Redis, for data storage. Apache Cassandra is utilized for perpetual archive. It is a scalable and highly available column oriented database suitable for time series data. Redis is used for the real time data cache because of a very fast in-memory key-value store. Data acquisition part of the new system was also built based on ZeroMQ message packed by MessagePack. The operation of the new system started in January 2015 after the long term evaluation over one year.

WED3O05	Big Data Analysis and Analytics with MATLAB	software, database, framework, controls	656
	D.S. Willingham ASCo, Clayton, Victoria, Australia
	Overview using Data Analytics to turn large volumes of complex data into actionable information can help you improve design and decision-making processes. In today's world, there is an abundance of data being generated from many different sources. However, developing effective analytics and integrating them into existing systems can be challenging. Big data represents an opportunity for analysts and data scientists to gain greater insight and to make more informed decisions, but it also presents a number of challenges. Big data sets may not fit into available memory, may take too long to process, or may stream too quickly to store. Standard algorithms are usually not designed to process big data sets in reasonable amounts of time or memory. There is no single approach to big data. Therefore, MATLAB provides a number of tools to tackle these challenges. In this paper 2 case studies will be presented: 1. Manipulating and doing computations on big datasets on light weight machines; 2. Visualising big, multi-dimensional datasets Developing Predictive Models High performance computing with clusters and Cloud Integration with Databases, HADOOP and Big Data Environments.

Maesaka, T. Ohshima, Y. Otake RIKEN SPring-8 Center, Sayo-cho, Sayo-gun, Hyogo, Japan T. Maruyama RIKEN/SPring-8, Hyogo, Japan
	At the X-ray Free Electron Laser (XFEL) facility, SACLA, an event-synchronized data acquisition system has been utilized for the XFEL operation. This system collects every shot-by-shot data, such as point data of the phase and amplitude of the RF cavity pickup signals, in synchronization with the beam operation cycle. This system also acquires RF waveform data every 10 minutes. In addition to the periodic waveform acquisition, an abnormal RF waveform that suddenly occurs should be collected for failure diagnostics. Therefore, we developed an abnormal RF waveform data acquisition (DAQ) system, which consists of the VME systems, a cache server, and a NoSQL database system, Apache Cassandra. When the VME system detects an abnormal RF waveform, it collects all related waveforms of the same shot. The waveforms are stored in Cassandra through the cache server. Before the installation to SACLA, we ensured the performance with a prototype system. In 2014, we installed the DAQ system into the injection part with five VME systems. In 2015, we will acquire waveforms from the low-level RF control system configured by 74 VME systems at the SACLA accelerator.

WEPGF038	A Flexible System for End-User Data Visualisation, Analysis Prototyping and Experiment Logbook	controls, laser, free-electron-laser, electron	782
	R. Borghes, V. Chenda, G. Kourousias, M. Lonza, M. Prica, M. Scarcia Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	Experimental facilities like synchrotrons and free electron lasers, often aim at well defined data workflows tightly integrated with their control systems. Still such facilities are also service providers to visiting scientists. The hosted researchers often have requirements different than those present in the established processes. The most evident needs are those for i) flexible experimental data visualisation, ii) rapid prototyping of analysis methods, and iii) electronic logbook services. This paper reports on the development of a software system, collectively referred to as DonkiTools, that aims at satisfying the aforementioned needs for the synchrotron ELETTRA and the free electron laser FERMI. The design strategy is outlined and includes topics regarding: dynamic data visualisation, Python scripting of analysis methods, integration with the TANGO distributed control system, electronic logbook with automated metadata reporting, usability, customization, and extensibility. Finally a use case presents a full deployment of the system, integrated with the FermiDAQ data collection system, in the free electron laser beamline EIS-TIMEX.

WEPGF044	Filestore: A File Management Tool for NSLS-II Beamlines	experiment, data-analysis, EPICS, database	796
	A. Arkilic, T.A. Caswell, D. Chabot, L.R. Dalesio, W.K. Lewis BNL, Upton, Long Island, New York, USA
	Funding: Brookhaven National Lab, Departmet of Energy NSLS-II beamlines can generate 72,000 data sets per day resulting in over 2 M data sets in one year. The large amount of data files generated by our beamlines poses a massive file management challenge. In response to this challenge, we have developed filestore, as means to provide users with an interface to stored data. By leveraging features of Python and MongoDB, filestore can store information regarding the location of a file, access and open the file, retrieve a given piece of data in that file, and provide users with a token, a unique identifier allowing them to retrieve each piece of data. Filestore does not interfere with the file source or the storage method and supports any file format, making data within files available for NSLS-II data analysis environment.

	C.H. Wang, L.F. Li IHEP, Beijing, People's Republic of China
	Funding: supported by NFSC(1137522) The old historical Oracle database in the BEPCII has been put into operation in 2006, there are some problems such as the program operation instability and EPICS PVs loss, a new data acquiring and query system with Oracle and EPICS has been developed with Eclipse and JCA. On one hand, the authors adopt the technology of the table-space and the table-partition to build a special database schema in Oracle. On another hand, based on RCP and Java, EPICS data acquiring system is developed successfully with a very friendly user interface. It's easy for users to check the status of each PV's connection, manage or maintain the system. Meanwhile, the authors also develop the system of data query, which provides many functions, including data query, data plotting, data exporting, data zooming, etc. This new system has been put into running for three years. It also can be applied to any EPICS control systems.

WEPGF122	Real-Time Performance Improvements and Consideration of Parallel Processing for Beam Synchronous Acquisition (BSA)	EPICS, timing, real-time, linac	992
	K.H. Kim, S. Allison, T. Straumann, E. Williams SLAC, Menlo Park, California, USA
	Funding: Work supported by the the U.S. Department of Energy, Office of Science under Contract DE-AC02-76SF00515 for LCLS I and LCLS II. Beam Synchronous Acquisition (BSA) provides a common infrastructure for aligning data to each individual beam pulse, as required by the Linac Coherent Light Source (LCLS). BSA allows 20 independent acquisitions simultaneously for the entire LCLS facility and is used extensively for beam physics, machine diagnostics and operation. BSA is designed as part of LCLS timing system and is currently an EPICS record based implementation, allowing timing receiver EPICS applications to easily add BSA functionality to their own record processing. However, the non-real-time performance of EPICS record processing and the increasing number of BSA devices has brought real-time performance issues. The major reason for the performance problem is likely due to the lack of separation between time-critical BSA upstream processing and non-critical downstream processing. BSA is being improved with thread level programming, breaking the global lock in each BSA device, adding a queue between upstream and downstream processing, and moving out the non-critical downstream to a lower priority worker thread. The use of multiple worker threads for parallel processing in SMP systems is also being investigated.

	M. Teichmann, B.C. Heisen, K. Weger, J. Wiggins XFEL. EU, Hamburg, Germany
	The Karabo GUI is a generic graphical user interface (GUI) which is currently developed at the European XFEL GmbH. It allows the complete management of the Karabo distributed control and data acquisition system. Remote applications (devices) can be instantiated, operated and terminated. Devices are listed in a live navigation view and from the self-description inherent to every device a default configuration panel is generated. The user may combine interrelated components into one project. Such a project includes persisted device configurations, custom control panels and macros. Expert panels can be built by intermixing static graphical elements with dynamic widgets connected to parameters of the distributed system. The same panel can also be used to graphically configure and execute data analysis workflows. Other features include an embedded IPython scripting console, logging, notification and alarm handling. The GUI is user-centric and will restrict display or editing capability according to the user's role and the current device state. The GUI is based on PyQt technology and acts as a thin network client to a central Karabo GUI-Server.

Apache Cassandra is utilized for perpetual archive. It is a scalable and highly available column oriented database suitable for time series data. Redis is used for the real time data cache because of a very fast in-memory key-value store. Data acquisition part of the new system was also built based on ZeroMQ message packed by MessagePack. The operation of the new system started in January 2015 after the long term evaluation over one year.

Overview using Data Analytics to turn large volumes of complex data into actionable information can help you improve design and decision-making processes. In today's world, there is an abundance of data being generated from many different sources. However, developing effective analytics and integrating them into existing systems can be challenging. Big data represents an opportunity for analysts and data scientists to gain greater insight and to make more informed decisions, but it also presents a number of challenges. Big data sets may not fit into available memory, may take too long to process, or may stream too quickly to store. Standard algorithms are usually not designed to process big data sets in reasonable amounts of time or memory. There is no single approach to big data. Therefore, MATLAB provides a number of tools to tackle these challenges. In this paper 2 case studies will be presented: 1. Manipulating and doing computations on big datasets on light weight machines; 2. Visualising big, multi-dimensional datasets Developing Predictive Models High performance computing with clusters and Cloud Integration with Databases, HADOOP and Big Data Environments.

At the X-ray Free Electron Laser (XFEL) facility, SACLA, an event-synchronized data acquisition system has been utilized for the XFEL operation. This system collects every shot-by-shot data, such as point data of the phase and amplitude of the RF cavity pickup signals, in synchronization with the beam operation cycle. This system also acquires RF waveform data every 10 minutes. In addition to the periodic waveform acquisition, an abnormal RF waveform that suddenly occurs should be collected for failure diagnostics. Therefore, we developed an abnormal RF waveform data acquisition (DAQ) system, which consists of the VME systems, a cache server, and a NoSQL database system, Apache Cassandra. When the VME system detects an abnormal RF waveform, it collects all related waveforms of the same shot. The waveforms are stored in Cassandra through the cache server. Before the installation to SACLA, we ensured the performance with a prototype system. In 2014, we installed the DAQ system into the injection part with five VME systems. In 2015, we will acquire waveforms from the low-level RF control system configured by 74 VME systems at the SACLA accelerator.

Experimental facilities like synchrotrons and free electron lasers, often aim at well defined data workflows tightly integrated with their control systems. Still such facilities are also service providers to visiting scientists. The hosted researchers often have requirements different than those present in the established processes. The most evident needs are those for i) flexible experimental data visualisation, ii) rapid prototyping of analysis methods, and iii) electronic logbook services. This paper reports on the development of a software system, collectively referred to as DonkiTools, that aims at satisfying the aforementioned needs for the synchrotron ELETTRA and the free electron laser FERMI. The design strategy is outlined and includes topics regarding: dynamic data visualisation, Python scripting of analysis methods, integration with the TANGO distributed control system, electronic logbook with automated metadata reporting, usability, customization, and extensibility. Finally a use case presents a full deployment of the system, integrated with the FermiDAQ data collection system, in the free electron laser beamline EIS-TIMEX.

NSLS-II beamlines can generate 72,000 data sets per day resulting in over 2 M data sets in one year. The large amount of data files generated by our beamlines poses a massive file management challenge. In response to this challenge, we have developed filestore, as means to provide users with an interface to stored data. By leveraging features of Python and MongoDB, filestore can store information regarding the location of a file, access and open the file, retrieve a given piece of data in that file, and provide users with a token, a unique identifier allowing them to retrieve each piece of data. Filestore does not interfere with the file source or the storage method and supports any file format, making data within files available for NSLS-II data analysis environment.

The old historical Oracle database in the BEPCII has been put into operation in 2006, there are some problems such as the program operation instability and EPICS PVs loss, a new data acquiring and query system with Oracle and EPICS has been developed with Eclipse and JCA. On one hand, the authors adopt the technology of the table-space and the table-partition to build a special database schema in Oracle. On another hand, based on RCP and Java, EPICS data acquiring system is developed successfully with a very friendly user interface. It's easy for users to check the status of each PV's connection, manage or maintain the system. Meanwhile, the authors also develop the system of data query, which provides many functions, including data query, data plotting, data exporting, data zooming, etc. This new system has been put into running for three years. It also can be applied to any EPICS control systems.

Beam Synchronous Acquisition (BSA) provides a common infrastructure for aligning data to each individual beam pulse, as required by the Linac Coherent Light Source (LCLS). BSA allows 20 independent acquisitions simultaneously for the entire LCLS facility and is used extensively for beam physics, machine diagnostics and operation. BSA is designed as part of LCLS timing system and is currently an EPICS record based implementation, allowing timing receiver EPICS applications to easily add BSA functionality to their own record processing. However, the non-real-time performance of EPICS record processing and the increasing number of BSA devices has brought real-time performance issues. The major reason for the performance problem is likely due to the lack of separation between time-critical BSA upstream processing and non-critical downstream processing. BSA is being improved with thread level programming, breaking the global lock in each BSA device, adding a queue between upstream and downstream processing, and moving out the non-critical downstream to a lower priority worker thread. The use of multiple worker threads for parallel processing in SMP systems is also being investigated.

The Karabo GUI is a generic graphical user interface (GUI) which is currently developed at the European XFEL GmbH. It allows the complete management of the Karabo distributed control and data acquisition system. Remote applications (devices) can be instantiated, operated and terminated. Devices are listed in a live navigation view and from the self-description inherent to every device a default configuration panel is generated. The user may combine interrelated components into one project. Such a project includes persisted device configurations, custom control panels and macros. Expert panels can be built by intermixing static graphical elements with dynamic widgets connected to parameters of the distributed system. The same panel can also be used to graphically configure and execute data analysis workflows. Other features include an embedded IPython scripting console, logging, notification and alarm handling. The GUI is user-centric and will restrict display or editing capability according to the user's role and the current device state. The GUI is based on PyQt technology and acts as a thin network client to a central Karabo GUI-Server.
