WECOAA04	Employing RTEMS and FPGAs for Beamline Applications at the APS	controls, photon, coupling, power-supply	27
	D. M. Kline, S. K. Ross ANL, Argonne
	At the Advanced Photon Source (APS), the power and flexibility of an Altera Cyclone-II FPGA combined with the Arcturus uC5282 embedded microprocessor running RTEMS, provides a low cost solution for implementing beamline applications. In this paper, we discuss the approach of coupling an Altera FPGA and the Arcturus uC5282 to implement a time-resolved 32-channel scaler, development using the Altera Quartus-II design environment and the RTEMS tools, as well as an ASYN based EPICS device driver and its integration to the standard scaler record support. Furthermore, we discuss how this approach has been applied to other control system applications, such as for photon counting and flexible CCD shutter timing control. By employing this approach, a variety of applications can be quickly developed on one hardware platform which realizes real-time performance within the FPGA and provide a cost effective EPICS IOC for exporting data to scientists and users.

WEPL032	Programming Interfaces for Reconfigurable Instruments	controls, monitoring, brilliance, diagnostics	91

	Application Programming Interfaces (APIs) provided by the manufacturers of the instruments for the accelerators are a very important part of the functionality. There are many interface standards (EPICS, TINE, Tango,…) and even same standard can be used in various ways. Important features of modern instruments are reconfigurability and embedded computing. The developers of instruments that need to be connected to a control system are facing different requirements: adherence to standard protocols and support of reconfigurable instruments with diverse capabilities with a consistent interface. Instrumentation Technologies has implemented a well accepted solution with its proprietary Control System Programing Interface (CSPI) layer and adapters for each standard protocol. There are new challenges like reconfigurability, quality of service, discovery and maintainability that are being addressed with improved Measurement and Control Interface.

THCOAA04	Diamond's transition from VME to fieldbus based distributed control	controls, photon, vacuum, optics	124
	I. J. Gillingham, T. M. Cobb, P. Hamadyk, M. T. Heron, S. C. Lay, R. Mercado, M. R. Pearson, N. P. Rees Diamond, Oxfordshire
	The interface lay of Diamond's accelerator and photon beamline control systems have predominately been implemented as VME based systems. Forthcoming control systems, for new photon beamlines, have requirements necessitating a divergence from Diamond's adopted design patterns, including a reduction in available rack space and the management of hardware obsolescence. To address these, a new standard based on PCs and Ethernet field buses to the instrumentation has been defined. This paper will present the new design, how the design transition is being effected and the key benefits to Diamond.

	The Canadian Light Source (CLS) has upgraded the safety system for its Linear Accelerator (Linac) in October 2009. IEC 61508 SIL 3 certified components and methods were adopted in the development of the new safety system. This paper describes the new safety system and outlines the lessons learned from the project in applying industrial safety rated PLC equipment in the development of safety system for CLS accelerator.

THPL026	ESS Controls Strategy and Control Box Concept	controls, target, linac, proton	183

	European Spallation Source (ESS) will be constructed by a number of partner institutions in an international collaboration, thus increasing organizational risk as control system integration will be performed by a large number of independent teams. From the earliest stages in the project a lot of effort will be put into standardization of hardware, software and development procedures. ESS will use EPICS control system and will build on the positive experience of SNS and ITER. The basic unit of standardization is called the Control Box, and consists of one or more input/output controller (IOC) computers, zero or more I/O modules, PLC subsystems and intelligent special-purpose controllers, with all the software and a fully integrated development environment support. In this article we present the challenges faced by the Control Box concept and the benefits it brings.
FRIOA01	Control systems for new large projects	controls, feedback, background, synchrotron	186
	R. Sabjan, J. Dedic, M. Plesko, I. Verstovsek, K. Zagar Cosylab, Ljubljana
	We discuss control systems of accelerators and similar projects that are presently still in design and early construction phases, such as FAIR, ESS, MedAustron, NSLS II, ITER, etc, and comparing them against the approaches of the last two decades and explain the new trends that are emerging: · From the organizational perspective, control system architectures are established earlier in the project, allowing them to adapt to the machine physics requirements better as well as allow for modeling and simulations. · In software, there is much less emphasis on custom codes than there was in the past. Instead, standard and off-the-shelf components and frameworks already used at existing accelerators are becoming the preferred choice, not only reducing risks, but also allowing for reuse and sharing. · In hardware and networks for real-time control and data acquisition, there is a strong trend from custom electronics development to standard and off-the-shelf solutions. This in particular applies to systems like timing, machine protection, BPMs and LL RF. When custom solutions are needed, flexible hardware technologies (e.g., FPGA) are chosen to allow for future extensibility.

FRCOAA05	Data Acquisition from heterogeneous sensor networks: the case of NEPTUNE Canada, the world largest cabled ocean observatory.	controls, monitoring, fibre-optics, optics	214
	B. Pirenne ONC, Victoria
	Ocean Sciences is at the crossroads: it is entering the brave new world of "Big Science". The first of a new generation of large facilities, the NEPTUNE Canada cabled ocean observatory (www.neptunecanada.ca) will be presented from the point of view of a sensor network composed of hundreds of diverse instruments. The challenges we faced will be reviewed, together with the selected network design, data management and data distribution approaches. Special emphasis will be placed on the architecture of the system and on the more recent developments and concepts used to help scientists in their exploitation of the data. Finally a number of the early discoveries made with the new facility will be briefly described.
