	We report the status and the upgrade of the event-synchronized data-acquisition system for the accelerator control of XFEL/SPring-8. Because the XFEL is composed of a linac, most of the equipment is driven with the pulsed operation. The stability of equipment is critically important to achieve/stabilize the FEL lasing. We need a fast data-acquisition system to take a set of data from RF signals and beam monitor signals synchronizing with the same electron beam shots. For this purpose, the event-synchronized data-acquisition system has been introduced to the control system of the SCSS test accelerator, an XFEL prototype machine. The system consists of a data filling computer, a relational data base server, VME-based shared memory boards and distributed shared memory network. So far total of 54 signals from the beam monitoring system are successfully collected synchronizing with the 60 Hz of beam operation cycles. The accumulated data was utilized for the fast feedback correction of beam trajectories and energy quite effectively. Signals from the RF systems will be taken by the upgraded data-acquisition system utilizing the distributed memory-cache system.
TUC003	Development of COM Express VME Carrier Board with Remote Management Capability	90

	VME market is shrinking gradually. We have recently faced with difficulty that our choice of VME CPU boards from the market has been restricted. Since over two hundreds of VME computers have been deployed, we have to solve the difficulty. We, therefore, design and develop a COM Express VME carrier board. It is equipped with the VME64x interface and the PICMG standardized COM Express interface. We can build up our VME CPU board by combining the carrier board with a suitable COM in the growing COM Express market. We design the carrier board to realize another solution for the difficulty. That is, the VMEbus can be controlled from its PMC/XMC slot without using a COM Express module. High-reliable server computer would be a VME controller via a PCI or PCI Express extension like Serial Rapid I/O, for example. In addition, we design the carrier board to support remote management functions. The daughter board attached onto the carrier will provide VME/COM monitoring function, VMEbus reset function and KVM (keyboard, video, mouse) over IP function via an independent network interface on the carrier. The design details and the available functions will be presented.
TUP067	Magnet Power Supply Control System Using i-DIO FPGA Program in a VME Filed Bus Card	236

	A Control system for the XFEL/SPring-8 magnet power supply was designed by using an FPGA program in the "i-DIO" card. This card is modified of the VME field bus card "Opt-VME DIO". An output current deviation, monitoring ADC data from DAC current set value, is checked and makes an alarm signal. The ADC data can be averaged in some special sequences commanded by an upper workstation. A local control system of the power supply is also achieved by the i-DIO. Magnet power supply total system and test operations with the newly developed i-DIO card will be reported.

TUP095	Facility Utility Control System of XFEL/SPring-8	298

	The XFEL facility under construction at SPring-8 requires highly stable RF phase and intensity control for steady X-ray lasing. The RF conditions are very sensitive to facility utilities and environmental conditions such as air temperature, power line voltage, especially to cooling water temperature for accelerating structures. We, therefore, have to monitor them with required sampling rate and resolution from the viewpoint of the accelerator control. In particular, the cooling water for accelerating structure should be controlled seamlessly from the XFEL control system to achieve steady lasing. We designed and constructed a control system for the facility utilities as a part of the XFEL accelerator control with the MADOCA framework. All the signals of the facility utilities are stored into the same database with the XFEL control system, which helps us to investigate the correlations between beam stability and environmental conditions. All the utility equipment is controlled by PLCs connected to VME systems through FL-net. We set up PLC touch panels to support daily management as the local control interface.
WEP091	Upgrade of the Accelerator Radiation Safety System for SPring-8	579

	The accelerator safety interlock system to protect persons from radiation hazard induced by electron beams and synchrotron radiation has been operating over a decade in SPring-8. This system is monitoring the safety condition of accelerator components and stops injection electron beams in case of the failure, and stored electron beams are aborted if necessary. SPring-8 complex is composed of five accelerator/beam-transport areas. The injection beam direction can be frequently changed between the two accelerator areas; SPring-8 storage ring and NewSUBARU storage ring. Therefore, the safety interlock system was built introducing the idea of the "operation mode" control system. Once one of the operation modes is selected, the electron beams transport route is defined uniquely. The operation mode control system manages the combination of some accelerator/beam-transport areas. Since the operation mode control system became complicated because the number of "operation mode" has increased according to SPring-8 upgrades, we are planning to construct new safety interlock system. We will report the status of the current safety interlock system and the conceptual design of the new one.

THP031	Upgrade of RF Control System at SPring-8	730

	SPring-8 continues its operation over 10 years. Recently, we encounter the need to replace commercial I/O boards due to manufacturing discontinuances. Also, early introduced GPIB control causes instabilities on our control system. In this paper, we report upgrade on these issues for RF control system at SPring-8. For the replacements of I/O boards, we needed some idea for restricted time due to short shutdown period of accelerator operation, and for large number of signals. Therefore, we developed new boards [analog input board (AI) and pulse train generator board (PTG)] for smooth replacements. The new boards were designed to have similar signal cabling scheme and software application with current system. Also, additional improvements (higher signal density, better resolution for AI, flexible logic with logic-reconfigurable VME board for PTG), were introduced at the same time. For AI, ~40 boards were successfully replaced in short time, then we achieved better resolution and reduction in number of boards. For the replacement of GPIB control, we introduced small embedded PC (Armadillo) instead of GPIB-RS-232C converter. Thus, we could improve the stability of the RF control system.

	The X-ray free electron laser (XFEL) facility is under construction at SPring-8. An rf test stand was build for the XFEL to assure performance of the delivered rf components under the high-power condition and to establish a conditioning procedure for stable operation with design rf power. In addition, the test stand is used to confirm a performance of a low-level rf system, a precise water temperature control system, a vacuum system and an rf high power system. In this paper we describe a software framework to control those equipment and test results of a newly developed software component include device drivers with Solaris 10 for x86.
