1. DCS 6.03.2007 T0 DCS Answers to DCS Commissioning and Installation related questions ALICE week 5.04.07 T.Karavicheva and the T0 team T0 DCS Answers to DCS Commissioning and Installation related questions ALICE week 5.04.07 T.Karavicheva and the T0 team

2. KEY dates –Commissioning on surface: “C” part of the detector is at CERN and was checked last October. The “A” part will arrive to the lab at CERN from Finland mid March –Detector installation in UX: 30 March – 4 April for “C” part. No access till August, when the “A” part goes down (planned 28-29 Aug). –Accessible for DCS: for tests in June, fully in August (DCS Commissioning 6-02-07)

3. T0-C is at CERN ready for installation T0-C T0-A T0-A arrived at CERN yesterday

4. SUB-SYSTEMS TO COMPLETE –HV/LV PVSS: Implemented in PVSS 3.1 and tested with final hardware. Already ported to 3.6, to be tested with the hardware. Action: Tatiana with her student FSM: Follows HMP and V0 design. Waiting for HW from repair. Target date: end February. Action: Tatiana. HW: –mainframe: delivered one week ago, but was broken (no boot screen). Returned to pool, no estimate for the repair time yet. Tatiana will check the status (DCS Commissioning 6-02-07)

5. Status [HV/LV] Hardware: SY1527 mainframe – in Lyon 3 x A1733N Power Supply Units –was tested by Electronics pool. A1733N are in T0 lab being tested -2 x A1533 LV Power Supply Unit, 6x10V/2.7A was received at CERN some days ago Software: 1. Use PVSS 3.6 t00_dcs project updated to 3.6 Framework 3.0.0 FSM updated to 3.6 ALICE UI 3.0* 2. Upgrading software version From PVSS V3.1 to PVSS V3.6 done at home Institutes, not yet tested with final hardware. 3.Will be tested during the March *) Start testing 05.03.2007

6. (DCS Commissioning 6-02-07) –FEE fast PVSS: DIM server connected to PVSS was used for tests in October. DIM server will be upgraded in February; final PVSS implementation depends on delivery of electronics (7 different types of modules) but will be ready before installation. Action: Tatiana and her student. Not yet done( Electronics production not yet completed)

7. Status [ Fast electronics ] Delivered at CERN: -A2818,V2718 Orded: 2 NIM crates with power supplies (PS) PS: Wiener Power supply UEP22 (300W), ( +/-5V / 17A, +/-12V / 3.4A, +/-24V / 3.4A). - Crate: Wiener 5U NIM crate Crate UEN03 12 slot card cage. 2 VME crate PS: Wiener 0P17.0711 Power- Supply 7237 6U (+5V/100A, +/-12V/10A). – Crate: Wiener 0B06.3B5J1: Card-Cage 7219 VME64x BIN, Local PSU, 21x6U, RP0 access, Mag tolerant. The crates with PS are expected to be delivered to CERN in March/April 2007. Modules: Electronics production not yet completed Ordered: 2 CAEN LED 895B

8. (DCS Commissioning 6-02-07) –FEE readout PVSS: not implemented. DIM server required to control DRM via A2818 or Ethernet – the software will be copied from TOF (Pietro Antonioli & Ombretta Pinazza), more details beginning of March. Action: Tatiana FSM: not implemented – target end March – action Tatiana HW CPDM/TRM: modules received from TOF last October, partial setup exists. Final modules to be delivered in March

9. Status [ Readout electronics ] Delivered at CERN: 2 TRMs, 1 CPDM, A2818 card, T0 Alice box -DRM (prototype delivered at CERN last weekend) was tested in Bologna DRM final version –end of April Ordered : A3486, A1676,A3000(filter) Software for DCS will be provided by TOF group : 1.PVSS project to control ALICE BOX 2. PVSS project to control DRM

10. Cabling for CAEN Easy 48V service power To power control part of the Easy crates/modul es Propose to add small power supply in same rack as branch controller We will take care of PS and cabling (From Andre Augustinus) Taken care of by DCS In UX racks In CR racks

11. Status [Laser Calibration] LaserAttenuator Ethernet-RS232 interface (Digi One) Hardware: ready for installation Software: 1. Standard: PVSS 3.6 + FSM PVSS exists, tested with hardware FSM: 1st version exists, but might be modified, depending on the calibration procedure(calibration procedure not yet fixed)

12. CFD Control (CANBERRA 454) ELMB&DAC for CFD. The versions tested in CERN: PVSS: 3.1 (3.1 with all patches) OPC server for ELMB: 2.9.1 (now avaible 2.9.1 - requires.net Framework 2.0) JCOP Framework: 2.3.6 (with installation tool - now avaible: 2.3.8 for PVSS 3.1 and 3.0 for PVSS 3.6). ELMB Framework 3.3.1 (now avaible: 3.3.3) I will try to update this to newest versions (including PVSS 3.6).

13. Crate control -L.Wallet will provide tools for VME crate Control. -NIM crate control (the same solution as for CFD) -readout VME crate (TOF solution)
