  1. RAMSES & ARCONRadiation Monitoring for the Environment and Safety Basics and Overview M. Widorski, DGS/RP EDMS 1118414

  2. RAMSES replaces ARCON

  3. Different concept for RAMSES

  4. Interfaces • Interlocks • SIL 2 hardware interlock • LASER connection • Alarms transmitted to LASER • DIP: Data Interchange Protocol • Access to RAMSES (some) real time data • Logging DB / Measurement DB • Access to RAMSES (some) historical data

  5. ARCON Hardware Remains …

  6. … old ARCON Supervision architecture

  7. ARCON – RAMSES – BRIDGE New …

  8. RAMSES2 LightSecuring the LHC injector chain New … • Installation of ~50 measuring channels at the PS and SPS to partially replace ARCON • All relevant installations for LHC operation now independent of ARCON • Parallel operation to ARCON in 2011 • Installation finished during short shutdown; acceptance tests ongoing • Alarm transmission to CCC to be finalised

  9. ARCON/RAMSES consoles CCC (PS) ARCON connection status Alarm repeater panel Dedicated ARCON Terminal, will be replaced by RAMSES console

  10. Alarm repeater (PS) Operational status Test button Alarm LED Acknowledge button Alarm is triggered: Sound + LED Acknowledgement: If alarm still present, LED remains, sound is stopped but repeated after 5 min LED disappears when alarms is acknowledged and off.

  11. ARCON connection panel (PS) If connection to ARCON is lost: Sound + LED Acknowledgement Upper panel shows which ARCON has been lost LED disappears when connection is re-established Connection lost = no alarm transmission on repeater

  12. RAMSES Alarm transmission DA Meas. Electronics Alarm creation RAMSES (CTF3) Alarm Unit Detector For all other detectors at CTF3 Interlock Interlock on safety chain: PAXCT211 PATCT201 Interlock DA Interlock ARCON EST DA Alarm Repeater (CCC, CTF3 CR)

  13. RAMSES Alarm transmission DA Meas. Electronics Alarm creation RAMSES2 light (PS) Alarm Unit Detector Interlock RAMSES Server Interlock DA Safety Chain Interlock DA PLC PLC Alarm Repeater

  14. ARCON Interlocks

  15. System failures Typical failures: • Network interruption, power failures • Alarm remains on although alarm conditions are off • Monitors stops working (BF alarm) • Monitors show abnormal high values • Software crashes (no alarms created, no alarms transmitted, no measurements stored or transmitted, “stable values”, no communication possible) Always contact DGS/RP (piquet or technician) in case of failures or doubts. Think failsafe !

  16. Actions summary ARCON: A Level - RAMSES: “Alarm” (red) •   Ascertain the cause of the alarm. • Take action to reduce the radiation levels. • If the radiation level cannot be reduced, contact DGS/RP. ARCON: B Level - RAMSES: “High Alarm” (red) • Stop the beam to the corresponding area. • Ascertain the cause of the alarm. • Take action to avoid further high radiation levels. • Note the alarm, its cause and actions taken in the logbook. • If the high radiation level persists, contact DGS/RP. Monitors or system fault • Identify the failure location and stop the beam to the corresponding area. • Contact DGS/RP, in order to put the system/monitor back into service. • The beam can be restarted once the fault has been eliminated or compensated.

  17. General Procedure SR16: What to do in case of a radiation alarm ?

  18. Specific: PS Complex Up to date information on interlocks available on: http://cern.ch/rp-ps

  19. Specific: SPS Complex Document specifying detailed action to be taken in case of system failures (EDMS 969891)

  20. ‘Applications’ Data flow DAI Historical data Real-time data DB SUPERVISION BRIDGE Server CWS Server CMSS Server PLC Real-time data ARCON Panel PC Data storage Local display MS DA Meas. Electronics Alarm creation Alarm Unit DA Detector Interlock

  21. Supervision (SUP) Data Analysis Interface (DAI) User applications

  22. Applications • Dedicated terminals in CR • Automatic NICE login • RAMSES Terminal Server • Personal NICE login • Supervision software login • Control rooms: generic login (spsop, psop, lhcop, …) • Other: personal login

  23. Authorisation levels • Visualisation • display of alarms, status, historical and real time data • Visualisation + Acknowledgment • + acknowledge alarms and events • Parameter + Configuration • + parameter and configure channels • Definition • + system modifications / installations • Developer • + programming / developing rights Operators RP / ENV
