  1. Answers to DCS questionsDetector: PHOS & CPV • PV1: 2 persons • PV2: prompt technical support of the detector PVSS developers • PV3: no • PV4: -- • PV5: -- Serguei Sadovsky, DCS meeting 23.09.04

  2. Answers to DCS questionsDetector: PHOS & CPV • OPC1: yes, CAEN 1527, A1833P • OPC2: we used CAEN 1527 independently via Ethernet (TCP/IP) • OPC3: -- Serguei Sadovsky, DCS meeting 23.09.04

  3. Answers to DCS questionsDetector: PHOS & CPV • FSM1: detector oriented HV/LV hierarchy: -> PHOS detector -> 5 PHOS modules -> ECAL module -> 4 HV + 6 LV -> CPV module -> 8 HV + 5 LV • FSM2: yes, 1 sec • FSM3: yes • FSM4: we suggest some modifications Serguei Sadovsky, DCS meeting 23.09.04

  4. Answers to DCS questionsDetector: PHOS & CPV • CO1: CERN RedHat 7.3.4 Linux as much as possible • CO2: root, StarOffice, e-mail, web • CO3: access via ssh (enough from CERN) and this will be sufficient to control any number of parameters • CO4: no essential additional data storage but all disks should be redundant (RAID) • CO5: lxplus, afs, DATE Serguei Sadovsky, DCS meeting 23.09.04

  5. Answers to DCS questionsDetector: PHOS & CPV • DB1: PHOS HV (40 channels) PHOS LV (35 channels) PHOS crystal temperature (45 channels) PHOS FEE temperature (25 channels) CPV HV (20 channels) CPV LV (25 channels) CPV LV PS temperature (10 channels) CPV gas mixture, pressure (5 channels) • DB2: PHOS & CPV HV/LV setting, see channel number above + 5 x 3584 APD HV setting + 5 x 3584 LED monitoring channel setting Serguei Sadovsky, DCS meeting 23.09.04

  6. Answers to DCS questionsDetector: PHOS & CPV • FE1: ones per run • FE2: ??? • FE3: the parameter list see in DB1, module status Flags: - ECAL cooling ON, ECAL temp. stabilized - ECAL LV ON, ECAL HV ON, ECAL ON - CPV LV ON, CPV HV ON, CPV ON - PHOS module ON • FE4: PHOS - calibration by physical data CPV - pedestal measurements Serguei Sadovsky, DCS meeting 23.09.04

  7. Answers to DCS questionsDetector: PHOS & CPV • RS1: yes, PHOS thermo-stabilization and thermo-monitoring system Serguei Sadovsky, DCS meeting 23.09.04

  8. Answers to DCS questionsDetector: PHOS & CPV • LV1: APD HV finest grain – 25 uA APD HV maximum current - 3 mA PHOS LV coarsest grain – 0.5 A PHOS LV maximum current- 100 A • LV2: yes • LV3: no Serguei Sadovsky, DCS meeting 23.09.04

  9. Answers to DCS questionsDetector: PHOS & CPV • PL1: in PHOS Lab, June 2005, the simplest DCS system for PHOS HV/LV ECAL • PL2: October 2006 Serguei Sadovsky, DCS meeting 23.09.04
