2. Thomas Jefferson National Accelerator Facility Page 2 Slow Controls Slow controls are for Configuring Monitoring Archiving The experiment Low Voltages. High Voltages Gas pressures Thresholds Targets Magnets Temperatures

3. Thomas Jefferson National Accelerator Facility Page 3 Slow Controls: Core System Experimental Physics and Industrial Control System Widely used and supported at national labs (eg ANL, BNL) Drivers for most hardware Already used for Hall-B / CLAS Expertise within collaboration Used at MCC Lots of on-site expertise Communication with other control sytems PCL, LabView

4. Thomas Jefferson National Accelerator Facility Page 4 Slow Controls: Hardware Support A list of “standard” supported hardware has been compiled Drivers exist (or will be written / updated) Detector groups strongly encouraged to use this. Identify non-standard hardware Develop drivers Time estimate: 1 person year.

5. Thomas Jefferson National Accelerator Facility Page 5 Slow Controls: Front End Control Systems Studio Eclipse-based collections of tools to monitor and operate large scale control systems, such as the ones in the accelerator community. Developed and used by many big labs (DESY, SNS, BNL) Maintained and supported Easy to develop user GUIs Tool to convert old style.adl GUIs. Will be used by Hall-D Much groundwork and testing already done. CSS already being tested on existing CLAS EPICS

6. Thomas Jefferson National Accelerator Facility Page 6 Slow Controls: Alarms Single table or tree view Sort by PV, Urgency, Severity.. Connect with: Other CSS components Variable passing, alarm timelines E log entries Send alarm PV to other PV tool Web reports Will be used by Hall-D Much groundwork and testing already done Best Ever Alarm System Integrated into CSS

8. Thomas Jefferson National Accelerator Facility Page 8 Slow Controls: Archiving CSS has integrated archiving RDB (Oracle, MySQL, PostgresSQL) Access to timelines etc – like live system. MCC have developed MYA MySQL base EPICS Archiver Already tested and used Offered as a service to other Halls CSS or MYA ? Hall D evaluated options - they will use MYA MYA integrated into CSS – best of both MCC developing this CLAS 12 will use MYA + CSS http://accelconf.web.cern.ch/accelconf/icalepcs2009/papers/wep021.pdf MYA – C. Slominski, Accel

9. Thomas Jefferson National Accelerator Facility Page 9 Slow Controls: Summary Core system: EPICSR3.14 Work well underway Supported hardware list produced Drivers ready within 1 year Front End: CSS (Control Systems Studio) Installation and testing in progress. Alarm: BEAST (Best Ever Alarm System) To be installed and tested over summer Archiving (MYA) To be set up over next year in consultation with MCC
