WECOMA02	Fast Orbit Correction at the Canadian Light Source	controls, storage-ring, wiggler, insertion	9
	C. G. Payne CLS, Saskatoon, Saskatchewan D. Chabot BNL, Upton, Long Island, New York
	Correction of the electron beam orbit in the storage ring at the Canadian Light Source has historically been implemented using a correction system capable of only moderate update rates. Over the past several years work has been undertaken to reduce orbit perturbations and improve end user synchrotron beam quality by reimplementing the correction system and enabling orbit corrections several orders of magnitude faster. This paper will describe the implementation and migration of the orbit control software from the slow correction system to the fast system.

WECOAA04	Employing RTEMS and FPGAs for Beamline Applications at the APS	controls, photon, coupling, instrumentation	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.

WEPL006	Status of the future SPIRAL2 Control System	controls, ion, radio-frequency, heavy-ion	38
	D. T. Touchard, P. Gillette, C. H. Haquin, E. Lecorche, E. Lemaitre, L. Philippe GANIL, Caen J. F. Denis, F. Gougnaud, J.-F. Gournay, Y. Lussignol, P. Mattei CEA, Gif-sur-Yvette P. G. Graehling, J. H. Hosselet, C. Maazouzi IPHC, Strasbourg Cedex 2
	For the study of fundamental nuclear physics, the Spiral2 facility, a driver accelerator followed by a rare ion production process, will be coupled with the existing Ganil machine to provide light and heavy exotic nuclei at extremely high intensities. To ease the collaboration with several institutes on the control system design, EPICS has been chosen as the basic framework and a specific care has been taken concerning the software organization and management. While first operational interfaces for power supplies, faraday cups or beam slits are already operational, a triggered fast acquisition system for beam diagnostics, a radiofrequency control system, and an emittance measurement system are going to be achieved. First EDM supervision screens and high level tuning applications based on EPICS/XAL framework have been designed. The use of relational databases, on the one hand for the design of an environment to generate the Epics databases, on the other hand to manage, set and archive meaningful values of the new facility, is under investigation. From the beginning of last year, two sources followed by their first beam line section have been tested. Promising results are presented.

WEPL020	EPICS applications in the control of SPES Target Laboratory	controls, target, diagnostics, extraction	67
	M. G. Giacchini, A. Andrighetto, G. Bassato, N. Conforto, L. Costa, L. Giovannini, J. A. Vasquez INFN/LNL, Legnaro (PD)
	The project of a new facility for the Selective Production of Exotic Species (SPES) has started at LNL. Radioactive ions will be produced by impinging an UCx target by a 70MeV, 200μA proton beam delivered by a commercial cyclotron. Then, the unstable ions will be accelerated by injecting them into the LNL superconducting LINAC. The construction of Target and Ion source prototype is at an advanced stage and, after more than two years spent in its construction, preliminary extraction tests were carried out with non-radioactive beams. The control of Target instrumentation is based on EPICS; we describe here the basic choices on hardware and software tools on both IOC and client side and give a brief description of last developments. * http://spes.lnl.infn.it http://www.aps.anl.gov/epics/ * http://www.lnl.infn.it/~epics/

THPL014	The ANKA B-Field Test Facility Control System, based on a SPEC Macro Package Enhanced Setup	controls, insertion, insertion-device, undulator	156
	K. Cerff, W. Mexner, T. Spangenberg Karlsruhe Institute of Technology (KIT), Karlsruhe
	The ANKA B-field test facility provides users with a flexible tool to investigate magnetic field distributions of different setups of coils or permanent magnets, optimal sensor types, geometrical arrangement and the possibility to change the independent physical stimuli to generate and alter magnetic field distributions. It is taken as an example of a straightforward device implementation with a recently introduced type of macro based ‘building block system’ for devices in spec. This macro package provides the C-like spec with an object orientated framework, with a namespace and class concept to represent the power supplies of different brands, probe positioning devices and measurement amplifiers. The device properties are stored as elements of an associative spec array, together with a set of standardized commands to access them. Their degree can be assumed to be volatile, private or public. The device properties can be initialized by default or synchronized with the values of the represented physical devices.

THPL018	Development of Image Processing System on Embedded EPICS for Beam Diagnostics	controls, monitoring, background, diagnostics	165
	J.-I. Odagiri, K. Furukawa, T. Obina, M. Satoh KEK, Ibaraki
	A new image processing system was developed based on EPICS and the FA-M3 PLC made by Yokogawa Electric Corporation. The hardware of the system comprises an F3RP61 CPU module running Linux and an F3UM02 frame grabber module. The CPU functions as an IOC to analyze the raw image data acquired and transferred by the frame grabber on the PCI-bus which connects the two modules. A custom record, graphicsRecord, holds the raw image data, the results of analysis and parameters set by the user over the network. GUI panels were created by using EDM in order to display the image and to set relevant control parameters into the fields of the graphicsRecord on the F3RP61-based IOC. It was confirmed that the developed system is able to acquire image data, analyze them appropriately, and send them over the network to a host computer to display the results of analysis. The design and results on performance measurement of the system is reported.

THPL022	Plans for monitoring TPS control system infrastructure using SNMP and EPICS	controls, monitoring, synchrotron, synchrotron-radiation	174

	The Taiwan Photon Source (TPS) control system is one of the crucial systems for the accelerators and beamlines. It is necessary to monitor the status of the control system components such as housekeeping parameters of cPCI EPICS IOC crates, network traffic, connections between computers, etc. The equipment room environment including electric power, temperature, fire alarm, and water leak will also need to be watched. Using Simple Network Management Protocol (SNMP), the behaviour of network-attached devices can be monitored for administrative attention. Since the TPS control system is based upon the EPICS framework, the monitoring system is planned to adopt the EPICS support with SNMP. This paper will describe the system architecture of this monitoring system.
