	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.

	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.

	Recent network system becomes more complex and larger because of virtual LAN and other virtualization technologies. Proliferation of a variety of network switches and routers makes a network system gigantic; hence, management of the misty network faces problems. This is the largest factor that deteriorates stable operation of a network system that should be robust and reliable. One of the promising solutions to keep a network system simple and understandable is introduction of the monitor tools that makes a network system visual and observable. We introduced the sFlow technology in addition to the traditional SNMP-based network node management (NNM) system. We could take statuses of network nodes by NNM such as hardware failure, and also we could grasp long perspective of network traffic at one view by the sFlow. In addition, an integrated log management system was introduced to collect all events on the whole network system. As a result, we could detect a trouble outbreak in real time even if a trouble occurred on the end point of the network, and could solve the problem promptly. We describe a way to achieve an observable network system to maintain stable network operation.
TUP061	Applications and Upgrading of Flexible and Logic-reconfigurable VME Board	221
	T. Hirono, T. Kudo, T. Ohata JASRI/SPring-8, Hyogo-ken
	We applied the flexible and logic-reconfigurable VME boards to many control systems, which requires fast and real-time control, such as a tag generating system and a pulse motor controller of 60Hz beam shutter. The board has a field programmable gate arrays (FPGA) chip for execution of user logic, which can be implemented in C. IO interfaces of the board are module cards. They can be mounted on the base board with connectors. The board was easily　modified by exchanging the IO modules and reconfiguring FPGA logic. We also upgraded the base board. The new board supports large data transition. The new board has PMC sockets with a PCI bus and a Gigabit Ether port. The same IO module card can also be used on the new board. and the upgraded board are shown in the presentation. The design and implementation of developing-evironment of the user logic of the board are shown with the applications. We also discuss about the design of the upgraded board.

	We have designed the control and the data acquisition system for the SPring-8 XFEL beamlines. The XFEL generates ultra-short pulsed coherent X-ray laser with the 60Hz beam repetition rate. Two-dimensional x-ray detectors are under development for X-ray detection. The data acquisition system for the detectors has to synchronize with the accelerator beam operation cycle to obtain correlations between incident X-ray and experimental data. The tagging system that records event numbers in the measurement data is especially important. The key technologies to make a success of the DAQ system of XFEL beamline are a tagging system of the 60Hz X-ray pulse, a real-time compression of fast massive data and low-latency network for data transfer. Both the network system of 3~4 Gbps bandwidth and the storage system with a near petabyte will be required in the initial operation phase of the XFEL project. At first, we developed a FPGA based tagging board that delivers tag numbers of X-ray pulse shots with parallel and serial interfaces. A first test system will be assembled by early 2010.
WEP028	Development of a Multi Functional Unit: Blanc4	465
	M. I. Ishii, T. Ohata JASRI/SPring-8, Hyogo-ken
	A beamline station control system in SPring-8 has been installing two types. One is a VMEbus system and another is a desktop PC-Based system. The VMEbus system was adopted to construct a flexible control system by combining VME modules. However, the VMEbus system is over engineering for a compact control system to handle a few I/O signals or a few motor axes. And the VMEbus system is hard to handle for beamline staffs who are not experts of control system. On the other hand, the desktop PC-Based system is relatively low-cost and suitable for small system. However, the system is inferior in stability and scalability to the VMEbus system. To construct a reliable, flexible, compact, low-cost and user-friendly system, we developed a multi functional unit, Blan4, that is a flexible embedded computer supporting COM Express basic form factor. A Blanc4 has two PCI slots and two PCI Express slots in just 1 U height. A Blanc4 can replace connector panels and signal conditioning boards customized for each control target. We report the Blanc4 assembling as a flexible multi functional unit.

	We develop the prototype control system of XFEL/SPring-8　undulator and confirm the capability of the system. The XFEL consists of the 8GeV linear accelerator and the undulators. The undulator is important for lasing of the intense X-ray beam. For the lasing, the required positioning accuracy of the undulator gap is less than 1 micrometer. We have to control the undulator gap to be less than sub-micrometer resolution. To realize, we control the undulators by the periodic feedback with the linear encoders. In this paper, we will describe detail design of the undulator control system on XFEL.

	Today, new synchrotron-radiation facilities have been built around the world. One of these facilities, RIKEN XFEL project in Japan, is characterized by its location beside existing facility, SPring-8. Using X rays from two facilities in coincidence, new scientific applications are expected such as pump-and-probe experiments, and so on. We also plan to use linac of the XFEL as another injector to the SPring-8. By benefiting from combined application with two facilities, it is necessary to integrate two control systems. Important point of the integration is combination and segregation of two facilities. For combined applications, two control systems should be treated as one facility. On the other hand, when two facilities are operated separately, two control systems should be independent each other, and one system must not be affected by any trouble of another system. To archive the point, we physically segregate control system into two networks using firewall. Since control architecture in SPring-8 is database oriented, two systems can be coupled with synchronization of database for combined applications. We show the concept and upgrade status of new network and 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.
