	While CERN's Super Proton Synchrotron (SPS) is able to deliver both secondary proton and primary ion beams to fixed targets in the North Area, the experimental areas (North Hall) are widely accessible during beam. In ion mode all normal safety elements involved in producing secondary beams are removed, so that an accidental extraction of a high-intensity proton beam into the North Hall would expose personnel present there to a radiation hazard. This has required an injector reconfiguration restricting operation to either ions or protons. However, demands for operational flexibility of CERN accelerators have led to a need to mix within the same SPS super-cycle both high-intensity proton cycles for LHC or HiRadMat and ion cycles for the North Area. We present an active interlock designed to mitigate this hazard: Beam Current Transformers are used to measure the level of beam intensity, and if above a set threshold, pulsing of the extraction septa is vetoed. The safety function is implemented by means of two logically equivalent but diverse and separate interlock chains. This interlock is expected to be in place once the SPS resumes operation after the first Long Shutdown in 2014.

	Funding: This work was supported by the U.S. Department of Energy, Office of Nuclear Physics, under Contract No. DE-AC02-06CH11357. The AMS (Accelerator Mass Spectrometry) project at ATLAS (Argonne Tandem Linac Accelerator System) complements the MANTRA (Measurement of Actinides Neutron TRAnsmutation) experimental campaign. To improve the precision and accuracy of AMS measurements at ATLAS, a new overall control system for AMS measurements needs to be implemented to reduce systematic errors arising from changes in transmission and ion source operation. The system will automatically and rapidly switch between different m/q settings, acquire the appropriate data and move on to the next setting. In addition to controlling the new multi-sample changer and laser ablation system, a master control program will communicate via the network to integrate the ATLAS accelerator control system, FMA control computer, and the data acquisition system.

MOPPC052	ESS Bilbao Interlock System Approach	interlocks, PLC, EPICS, controls	206
	D.P. Piso, I. Arredondo, M. Eguiraun, S. Varnasseri ESS Bilbao, Zamudio, Spain
	Funding: ESS Bilbao This paper describes the approach used at ESS Bilbao initiative for the implementation of the Interlock System. The system is divided into two parts depending on the required speed for the system response: Slow Interlocks (>100 msec.) and Fast Interlocks (<100 msec.). Besides, both interlocks parts are arranged in two layers: Local Layer and Master Layer. The Slow Interlocks subsystem is based on PLCs. This solution is being tested in the ESS Bilbao ECR ion source with positive results and the first version design is now complete for the LEBT system. For the Fast Interlocks local layer part, a solution based on NI cRIO has been designed and tested. In these tests a maximum response time of 3.5 μs. was measured for analog acquisition, threshold comparison and signal generation. For digital signals the maximum time response of a similar process was 500 nsec. . These responses are considered valid for the standard need of the project. Finally, to extract information from the interlocks system and monitor it, the Modbus/EPICS interface is used for Slow Interlocks, while EPICS output is produced by NI cRIO. Hence, it is planned to develop a light pyQT solution to perform this task.

MOPPC064	A New Spark Detection System for the Electrostatic Septa of the SPS North (Experimental) Area	high-voltage, controls, cathode, septum	246
	R.A. Barlow, B. Balhan, J. Borburgh, E. Carlier, C. Chanavat, T. Fowler, B. Pinget CERN, Geneva, Switzerland
	Electrostatic septa (ZS) are used in the extraction of the particle beams from the CERN SPS to the North Area experimental zone. These septa employ high electric fields, generated from a 300 kV power supply, and are particularly prone to internal sparking around the cathode structure. This sparking degrades the electric field quality, consequently affecting the extracted beam, vacuum and equipment performance. To mitigate these effects, a Spark Detection System (SDS) has been realised, which is based on an industrial SIEMENS S7-400 programmable logic controller and deported Boolean processors modules interfaced through a PROFINET fieldbus. The SDS interlock logic uses a moving average spark rate count to determine if the ZS performance is acceptable. Below a certain spark rate it is probable that the ZS septa tank vacuum can recover, thus avoiding transition into a state where rapid degradation would occur. Above this level an interlock is raised and the high voltage is switched off. Additionally, all spark signals acquired by the SDS are sent to a front-end computer to allow further analysis such as calculation of spark rates and production of statistical data.

	MedAustron is a synchrotron based centre for light ion therapy under construction in Austria. The accelerator and its control system entered the on-site commissioning phase in January 2013. This contribution presents the current status of the accelerator operation and commissioning procedure framework called ProShell. It is used to model measurement procedures for commissioning and operation with Petri-Nets. Beam diagnostics device adapters are implemented in C#. To illustrate its use for beam commissioning, procedures currently in use are presented including their integration with existing devices such as ion source, power converters, slits, wire scanners and profile grid monitors. The beam spectrum procedure measures distribution of particles generated by the ion source. The phase space distribution procedure performs emittance measurement in beam transfer lines. The trajectory steering procedure measures the beam position in each part of the machine and aids in correcting the beam positions by integrating MAD-XX optics calculations. Additional procedures and (beam diagnostic) devices are defined, implemented and integrated with ProShell on demand as commissioning progresses.

	RIKEN Radioactive Isotope Beam Factory (RIBF) is a heavy-ion accelerator facility producing unstable nuclei and studying their properties. After the first beam extraction from Superconducting Ring Cyclotron (SRC), the final stage accelerator of RIBF, in 2006, several kinds of updates have been performed. We will here present two projects of large-scale experimental instrumentations to be introduced in RIBF that offer new type of experiments. One is an isochronous storage ring aiming at precise mass measurements of short-lived nuclei (Rare RI ring), and the other is construction of a new beam transport line dedicated to more effective generation of seaweed mutation induced by energetic heavy ions. In order to control them, the EPICS-based RIBF control system is now under upgrading. Each device used in new experimental instrumentations is controlled by the same kind of controllers as those existing, such as Programmable Logic Controllers (PLCs). On the other hand, we have first introduced Control System Studio (CSS) for operator interface. We plan to set up the CSS not only for new projects but also for the existing RIBF control system step by step.

	The accelerator control system for the MedAustron light-ion medical particle accelerator has been designed under the guidance of CERN in the scope of an EBG MedAustron/CERN collaboration agreement. The core is based on the SIMATIC WinCC OA SCADA tool. Its open API and modular architecture permitted CERN to extend the product with features that go beyond traditional supervisory control and that are vital for directly operating a particle accelerator. Several extensions have been introduced to make WinCC OA fit for accelerator control: (1) Near real-time data visualization, (2) external application launch and monitoring, (3) accelerator settings snapshot and consistent restore, (4) generic panel navigation supporting role based permission handling, (5) native integration with interactive 3D engineering visualization, (6) integration with National Instruments based front-end controllers. The major drawback identified is the lack of support of callbacks from C++ extensions. This prevents asynchronous functions, multithreaded implementations and soft real-time behaviour. We are therefore striving to search for support in the user community to trigger the implementation of this function.

	MedAustron is a light-ion accelerator cancer treatment facility built on the green field in Austria. The accelerator, its control systemand protection systems have been designed under the guidance of CERN within the MedAustron – CERN collaboration. Building construction has been completed in October 2012 and accelerator installation has started in December 2012. Readiness for accelerator control deployment was reached in January 2013. This contribution gives an overview of the accelerator control system project. It reports on the current status of commissioning including the ion sources, low-energy beam transfer and injector. The major challenge so far has been the readiness of the industry supplied IT infrastructure on which accelerator controls relies heavily due to its distributed and virtualized architecture. After all, the control system has been successfully released for accelerator commissioning within time and budget. The need to deliver a highly performant control system to cope with thousands of cycles in real-time, to cover interactive commissioning and unattended medical operation were mere technical aspects to be solved during the development phase.

	The HIT (Heidelberg Ion Therapy) center is the first dedicated European accelerator facility for cancer therapy using both carbon ions and protons, located at the university hospital in Heidelberg. It provides three fully operational therapy treatment rooms, two with fixed beam exit and a gantry. We are currently developing a web based reporting tool for accelerator operations. Since medical treatment requires a high level of quality assurance, a detailed reporting on beam quality, device failures and technical problems is even more needed than in accelerator operations for science. The reporting tools will allow the operators to create their shift reports with support from automatically derived data, i.e. by providing pre-filled forms based on data from the Oracle database that is part of the proprietary accelerator control system. The reporting tool is based on the Python-powered CherryPy web framework, using SQLAlchemy for object relational mapping. The HTML pages are generated from templates, enriched with jQuery to provide a desktop-like usability. We will report on the system architecture of the tool and the current status, and show screenshots of the user interface. [1] Th. Haberer et al., “The Heidelberg Ion Therapy Center”, Rad. & Onc.,

THPPC002	Configuration Management for Beam Delivery at TRIUMF/ISAC	ion-source, database, ISAC, controls	1094
	J.E. Richards, K. Ezawa, R. Keitel TRIUMF, Canada's National Laboratory for Particle and Nuclear Physics, Vancouver, Canada
	The ISAC facility at TRIUMF delivers simultaneous beams from different ion sources to multiple destinations. More beams will be added by the ARIEL facility which is presently under construction. To ensure co-ordination of beam delivery, beam path configuration management has been implemented. The process involves beam path selection, configuration setup and configuration monitoring. In addition save and restore of beam line device settings, scaling of beam optic devices for beam energy and mass, beam path specific operator displays, the ability to compare present and previous beam tunes, and alarm enunciation of device readings outside prescribed ranges are supported. Design factors, re-usability strategies, and results are described.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. The Electron Beam Ion Source (EBIS) began operating as a pre-injector in the C-AD RHIC accelerator complex in 2010. Historically, C-AD RHIC pre-injectors, like the 200MeV Linac, have had largely independent timing systems that receive a minimal number of triggers from the central C-AD timing system to synchronize the injection process. The EBIS timing system is much more closely integrated into central C-AD timing, with all EBIS machine cycles included in the master supercycle that coordinates the interoperation of C-AD accelerators. The integrated timing approach allows better coordination of pre-injector activities with other activities in the C-AD complex. Independent pre-injector operation, however, must also be supported by the EBIS timing system. This paper describes the design of the EBIS timing system and evaluates experience in operational management of EBIS timing.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. The NASA Space Radiation Laboratory (NSRL) at BNL uses many different beams to do experiments associated with evaluating the possible risks to astronauts in space environments. This facility became operational in 2003 and operates from the AGS Booster synchrotron. In order to simulate the space radiation environment some of these experiments need to make use of beams of various energies. To simulate solar flare events, we implemented the Solar Particle Simulator in 2005. This system put in modifications to the accelerator controls to allow beam energies to be changed automatically, enabling target samples to be irradiated with many energies of the same type of ion, without having to make use of degraders. To simulate Galactic Cosmic events, they need to also be able to automatically change the ions used to irradiate a single sample. This project aims to allow NSRL to change ions as well as beam energies within a very short period of time. To do this requires modifications to existing controls as well as building new controls for a laser ion source. In this paper we describe NSRL, our plans to implement the Galactic Cosmic Event Simulator, and the status of the laser ion source.

The NASA Space Radiation Laboratory (NSRL) at BNL uses many different beams to do experiments associated with evaluating the possible risks to astronauts in space environments. This facility became operational in 2003 and operates from the AGS Booster synchrotron. In order to simulate the space radiation environment some of these experiments need to make use of beams of various energies. To simulate solar flare events, we implemented the Solar Particle Simulator in 2005. This system put in modifications to the accelerator controls to allow beam energies to be changed automatically, enabling target samples to be irradiated with many energies of the same type of ion, without having to make use of degraders. To simulate Galactic Cosmic events, they need to also be able to automatically change the ions used to irradiate a single sample. This project aims to allow NSRL to change ions as well as beam energies within a very short period of time. To do this requires modifications to existing controls as well as building new controls for a laser ion source. In this paper we describe NSRL, our plans to implement the Galactic Cosmic Event Simulator, and the status of the laser ion source.
