  SDA (Sequenced Data Acquisition) Time Intervals is a hierarchical logging system for describing complex large-scale repeated processes. SDA has been used extensively at Fermilab* for fine tuning during the Tevatron Collider Run II. SDA Time Intervals is a new system born during discussions between CERN and FNAL about routinely recording relevant data for the LHC. Its main advantages are extremly low maintenance and good integration with traditional "flat" dataloggers. The Time Intervals (TI) system records the time of key events during a process and relates these events to the data that the traditional datalogger archives. From the point of view of the application program, any number of datalogging systems can be refactored into human-understandable time intervals.

  We describe the control system for the new Frascati injector project (SPARC). The injector starts operation in fall 2007, and at that time the control system must be fully operative and integrate all tools to help the machine operation. To allow a fast development of the control system, we made some choices: (1) Labview as developing system due to its diffusion in the Frascati labs and being a standard-de-facto in the acquisition software; (2) GigaBit Ethernet as interconnection bus in order to have sufficient bandwidth for data exchange; and (3) PCs as front-end CPUs and operator console because they have enough computing power. In 2006 a first operation of the control system, during the SPARC gun test performed with the e-meter diagnostic apparatus, allowed us to test the architecture of the control system both from the hardware and software points of view. All control applications for magnetic elements, vacuum equipment, RF cavities, and some diagnostics have been developed and debugged online. An automatic process stores in a database operating information both periodically and on data change. Information can be sent automatically or manually to our e-logbook.  
 
TPPB35 The Control System for the TITAN Experiment at ISAC controls, ion, rfq, extraction 238

  The TITAN experiment at the ISAC radioactive beam facility consists of an RF cooler system, a Magnetic Penning Trap (MPET), and an Electron Beam Ion Trap (EBIT). These three systems may run together or independently. This paper describes the EPICS-based TITAN control system, which was modeled after the ISAC control system to facilitate integration. Both software and hardware configurations will be described, with emphasis on pulsed diagnostics and the pulse distribution system for synchronizing the traps in different operation modes.

  The XAL application development environment has been installed as a part of the control system for the Japan Proton Accelerator Research Complex (J-PARC) in Tokai, Japan. XAL was initially developed at SNS and has been described at length in previous conference proceedings (e.g., Chu et. al. APAC07, Galambos et. al. PAC05, etc.). We outline the upgrades and enhancements to the XAL online model necessary for accurate simulation of the J-PARC linac. For example, we have added permanent magnet quadrupoles and additional space charge capabilities such as off-centered and rotated beams and bending magnets with space charge. In addition significant architectural refactoring was performed in order to incorporate the current, and past, upgrades into a robust framework capable of supporting future control operations. The architecture and design of XAL is as important as its function, as such, we also focus upon the revised architecture and how it supports a component-based, software engineering approach.

RPPB24 Processing and Visualization of EPICS Data with MATLAB Applications controls, diagnostics, SNS 659

  To conserve control system resources it is often desirable to run compute-intensive real-time data processing applications on a dedicated host computer. In the EPICS-based control system of the ISAC radioactive beam facility, the Extensible Display Manager tool (EDM) is used for the operator interface. EDM screens control data acquisition and processing and provide visualization of the processed data. Matlab is used as the data processing engine. A number of Matlab applications were created in collaboration with the beam physics group. These applications are running on a dedicated Linux host, using EPICS Matlab Channel Access (MCA) to obtain raw data from beam diagnostic IOCs (Linux-based) and store the processed results in the IOC. The raw data are provided to the IOC by fast data acquisition applications through a shared memory interface.
