Fermilab's homegrown fire and security system (known as FIRUS) is highly reliable and has been used nearly thirty years. The system has gone through some minor upgrades, however, none of those changes made significant, visible changes. In this paper, we present a major overhaul to the system that is halfway complete. We discuss the use of Apple's OS X for the new GUI, upgrading the servers to use the Erlang programming language and allowing limited access for iOS and Android-based mobile devices.

TUCAUST02 SARAF Control System Rebuild 567

  The Soreq Applied Research Accelerator Facility (SARAF) is a proton/deuteron RF superconducting linear accelerator, which was commissioned at Soreq NRC. SARAF will be a multi-user facility, whose main activities will be neutron physics and applications, radio-pharmaceuticals development and production, and basic nuclear physics research. The SARAF Accelerator Control System (ACS) was delivered while still in development phase. Various issues limit our capability to use it as a basis for future phases of the accelerator operation and need to be addressed. Recently two projects have been launched in order to streamline the system and prepare it for the future development of the accelerator. This article will describe the plans and goals of these projects, the preparations undertaken by the SARAF team, the design principles on which the control methodology will be based and the architecture which is planned to be implemented. The rebuilding process will take place in two consecutive projects. The first will revamp the network architecture and the second will involve the actual rebuilding of the control system applications, features and procedures.

  To reach the goals specified in the ESRF upgrade program [1], for the new experiments to be built, the storage ring needs to be modified. The optics must to be changed to allow up to seven meter long straight sections and canted undulator set-ups. Better beam stabilization and feedback systems are necessary for the nano-focus experiments planned. Also we are undergoing a renovation and modernization phase to increase the lifetime of the accelerator and its control system. This paper resumes the major upgrade projects, like the new BPM system, the fast orbit feedback or the ultra small vertical emittance, and their implications on the control system. Ongoing modernization projects such as the solid state radio frequency amplifier or the HOM damped cavities are described. Software upgrades of several sub-systems like vacuum and insertion devices, which are planned for this year or for the long shutdown period beginning of 2012 are covered as well. The final goal is to move to a Tango only control system.

TUCAUST04 Changing Horses Mid-stream: Upgrading the LCLS Control System During Production Operations 574

  The control system for the Linac Coherent Light Source (LCLS) began as a combination of new and legacy systems. When the LCLS began operating, the bulk of the facility was newly constructed, including a new control system using the Experimental Physics and Industrial Control System (EPICS) framework. The Linear Accelerator (LINAC) portion of the LCLS was repurposed for use by the LCLS and was controlled by the legacy system, which was built nearly 30 years ago. This system uses CAMAC, distributed 80386 microprocessors, and a central Alpha 6600 computer running the VMS operating system. This legacy control system has been successfully upgraded to EPICS during LCLS production operations while maintaining the 95% uptime required by the LCLS users. The successful transition was made possible by thorough testing in sections of the LINAC which were not in use by the LCLS. Additionally, a system was implemented to switch control of a LINAC section between new and legacy control systems in a few minutes. Using this rapid switching, testing could be performed during maintenance periods and accelerator development days. If any problems were encountered after a section had been switched to the new control system, it could be quickly switched back.

TUCAUST05 New Development of EPICS-based Data Acquisition System for Millimeter-wave Interferometer in KSTAR Tokamak 577

  After achievement of first plasma in 2008, Korea Superconducting Tokamak Advanced Research (KSTAR) is going to be performed in the 4nd campaign in 2011. During the campaigns, many diagnostic devices have been installed for measuring the various plasma properties in the KSTAR tokamak. From the first campaign, a data acquisition system of Millimeter-wave interferometer (MMWI) has been operated to measure the plasma electron density. The DAQ system at the beginning was developed for three different diagnostics having similar channel characteristics with a VME-form factor housing three digitizers in Linux OS platform; MMWI, H-alpha and ECE radiometer. However, this configuration made some limitations in operation although it had an advantage in hardware utilization. It caused unnecessarily increasing data acquired from the other diagnostics when one of them operated at higher frequency. Moreover, faults in a digitizer led to failure in data acquisition of the other diagnostics. In order to overcome these weak points, a new MMWI DAQ system is under development with a PXI-form factor in Linux OS platform and main control application is going to be developed based on EPICS framework like other control systems installed in KSTAR. It also includes MDSplus interface for the pulse-based archiving of experimental data. Main advantages of the new MMWI DAQ system besides solving the described problems are capabilities of calculating plasma electron density during plasma shot and display it in run-time. By this the data can be provided to users immediately after archiving in MDSplus DB.

TUCAUST06 Event-Synchronized Data Acquisition System of 5 Giga-bps Data Rate for User Experiment at the XFEL Facility, SACLA 581

  A data acquisition (DAQ), control, and storage system has been developed for user experiments at the XFEL facility, SACLA, in the SPring-8 site. The anticipated experiments demand shot-by-shot DAQ in synchronization with the beam operation cycle in order to correlate the beam characteristics, and recorded data such as X-ray diffraction pattern. The experiments produce waveform or image data, of which the data size ranges from 8 up to 48 M byte for each x-ray pulse at 60 Hz. To meet these requirements, we have constructed a DAQ system that is operated in synchronization with the 60Hz of beam operation cycle. The system is designed to handle up to 5 Gbps data rate after compression, and consists of the trigger distributor/counters, the data-filling computers, the parallel-writing high-speed data storage, and the relational database. The data rate is reduced by on-the-fly data compression through front-end embedded systems. The self-described data structure enables to handle any type of data. The pipeline data-buffer at each computer node ensures integrity of the data transfer with the non-real-time operating systems, and reduces the development cost. All the data are transmitted via TCP/IP protocol over GbE and 10GbE Ethernet. To monitor the experimental status, the system incorporates with on-line visualization of waveform/images as well as prompt data mining by 10 PFlops scale supercomputer to check the data health. Partial system for the light source commissioning was released in March 2011. Full system will be released to public users in March 2012.
