  1. DCS WG report FV

  2. DCS activities (April – August) • LAV storage area temperature monitoring system • Photo (Valeri) • Last Screenshot (Jonas) • HV system – participation in tender preparation • User Requirements • Definition of Hierarchical Control and detector operation models. Twooptions are under evaluation. • LHC like • NA48 like • Users survey concerning of 2 special cases of system behavior during data taking: • Should we allow an automatic HV channel trip recovery (YES with parameterization) • Should we allow playing with individual HV(LV) channel (YES with special flag) • Strong appeal for general policy • User Interface • Study of other experiments examples (CMS, COMPASS). Other will come soon. • Generic HV channel panels (screenshot: Roman) • Sub-detector URD. RICH use case • First DCS users meeting (yesterday) VF

  3. DCS activities (April – August) ORACLE DB CS-CCR-PVSS5 data server KONTRON front-end PC CAN branch power supply PLC based digital I/O ELMB based antilog signals reading VME based CPU: DIM server SY2527 27 transceivers PS’s 4 preamplifiers PS’s 64 regulator boards: about 500 channels in total Custom made HV system ... • LKr High and Low voltage vertical slice • Intro: already existing hardware (photos - Valeri) • General view: VF

  4. DCS roadmap • June 2011 – LKr calorimeter vertical slice • Main goal: First vertical slice from sensors to user interface panels • Hardware • Transceiver and Preamplifier power supplies (ELMB + PLC) • HV system: CAEN SY2527 with A1832P board + Custom HV electronics (VME processor + DIM) • Software • LKr HV system DIM implementation with In_beam/Out_of_beam reading • ELMB + PLC combined objects (LKR LV system) • Prototype of FSM + operation models • Integration of LKr cryogenic control system information • Middle of October 2011 – Integration run • Main goals: First attempt of external contribution integration. Assessment of CPU power. • Hardware • LKr (~ 600 channels) • 3 ISEG HV power supplies with a few loaded channels (~750 channels) • STRAW tracker hardware (1 module ~ 500 channels) • RICH HV system with a few loaded channels (500 channels) • About 1250 channels in total – ¼ of full system • Sergey Sergeev should come at least 2 weeks in advance VF

  5. DCS roadmap - 2 • April 2012 – Full scale test run • Main goal: Validation of all control solutions and confirmation of CPU power. • Hardware : all detectors participating in Technical Run • 7-8 (10 (or 9) ) LAV stations: HV + some FE crates • 2-3 (3 or 4 ) STRAW tracker modules: HV+LV+ELMBs • MUV (full system): HV + ELMBs • CEDAR (full system): HV + FE crate (NINO)?+ ELMBs + cooling system? • CHOD (existing NA48)? • 50-70% of hardware participating in TR • Software • Final version of everything including FE control and crates • Can we integrate vacuum information ? • External development (and developers) should be available 2-3 weeks in advance VF
