  1. Gas system Commissioningprocedures and status S. Haider PH/DT1

  2. Overview • What is commissioning for us • Status • Alice • Atlas • Plans for 2007 • Conclusions Gas system commissioning Dec 2006 S.Haider PH/DT1

  3. 10 • Leak + functional test • Verification (pipes+cables) 5 Production cycles of the gas system hardware • Construction • Installation • Commissioning • Running-in Gas system commissioning Dec 2006 S.Haider PH/DT1

  4. Lab tests 60 Production cycles of the gas system software • Collect options • Production of code • Installation Gas system commissioning Dec 2006 S.Haider PH/DT1

  5. Commissioning steps (1/2) In general Commissioning is a Verification of functionality (hardware + software debugging phase) • Installation of PLC, WebMas and PVSS software • Test Profibus and CANbus lines from PLC to field nodes • Cable check from control racks to gas racks • With control interface we take output objects into manual mode and operate them (valves, pumps, MFCs, LEDs,…) • For input devices we: • Take off the device-connector in the rack and observe the state change on the control interface • Provoke a reading with a change of pressure or flow in an other part of the system.

  6. 1) computers 2)+3) cable IO check 4) 1st parameters 5) New functionality 6) interlocks 7) Leak tightness 8) Gas to chamber Commissioning steps (2/2) • Activate first set of parameters • Verify new functionality (where applicable) • Eg MDT mixer with liquid injection,- or RPC humidifier • Verify chamber pressure interlocks • Verify leak tightness of inter-area piping • Run gas through chambers Gas system commissioning Dec 2006 S.Haider PH/DT1

  7. Status • The following slides do not take into account: • Purifiers • Membranes • Liquifiers • Analysis modules • Only racks installed up to NOW are considered Gas system commissioning Dec 2006 S.Haider PH/DT1

  8. n/a 100% ok 1 rack of 2 ok not applicable to be done ALICE commissioning status Dec 2006 1/2 Gas system commissioning Dec 2006 S.Haider PH/DT1

  9. n/a all installed ok 1 rack of 2 ok not applicable to be done ATLAS commissioning status Dec 2006 1/2 Gas system commissioning Dec 2006 S.Haider PH/DT1

  10. Most commonly found mistakes • Cable + pneumatic lines • Swapped • Wrong labeled • Come to wrong rack in UX • Cut BUT: - “Whatever can be fixed within one day is not considered a mistake !” - MDT has 304 pneumatic lines of which only ~ 15 were wrong !!!

  11. Commissioning Estimate vs reality up to now days S all ~ 60!!! ……….ATLAS………. …CMS… ……………ALICE…………….. ……..LHCb…….. Gas system commissioning Dec 2006 S.Haider PH/DT1

  12. IT/CO software Installation work Commissioning CMS IT/CO Analysis, updates, etc… Purifier+Membrane instal. Commissioning of Purif+Membr. ATLAS BIG Wheels TOTEM Commissioning plan for 2007 2007 Jan Feb Mar Apr May Jun Jul Aug Sep IT/CO software Installation work Commissioning LHCb Gas system commissioning Dec 2006 S.Haider PH/DT1

  13. Conclusions • Commissioning procedures are very well tuned by now. • The teams ( ours + IT/CO) work extremely efficiently • ALICE and ATLAS systems will be ready to deliver gas to chambers by end Jan 2007 (installed racks only) • By about July 07all gas systems(but TOTEM) will/should be commissioned • No “show stoppers” in sight so far (let’s keep fingers crossed…) Gas system commissioning Dec 2006 S.Haider PH/DT1
