  1. SPD Control System: status report Domenico Elia – INFN Bari • Updates to the URD • Global Detector Control Layout • Prototyping activities ALICE DCS workshop - March 10, 2003

  2. Updates to the URD • HV system: none • LV system: • type and location of PS sources • type, number and location of Voltage Regulators • preliminary cabling scheme • FERO: preliminary architecture overview (Peter) • Cooling: more detailed description (meeting with ST/CV people this week) ALICE DCS workshop - March 10, 2003

  3. VRs Internal PP 10 mt 30 mt LV PS and Voltage Regulators Current scheme: • regulators outside magnet door (>10 mt from SPD): • no need for rad-hard devices • spaces, cabling, cooling issues much less critical • reduced amount of power lines (A+D grouping): • 2 regulators each half-stave (instead of 7) • 1 LV power source each half-sector (instead of 2) ALICE DCS workshop - March 10, 2003

  4. Cabling scheme (I) ALICE DCS workshop - March 10, 2003

  5. Cabling scheme (II) ALICE DCS workshop - March 10, 2003

  6. SPD Control sub-systems (I) SPD HV LV FERO Cooling Equipment bias PS V/I-monitor plant VME crate V-reg. board temperature detector configuration ALICE DCS workshop - March 10, 2003

  7. SPD Control sub-systems (II) • High Voltage: - 1 CAEN SY1527 crate (located in counting room) - 10 A1519 boards (floating 12 ch., 250V/1mA) - cables: 120 micro-coax Ethernet CAEN 1 crate PX UX 120 channels SPD ALICE DCS workshop - March 10, 2003

  8. SPD Control sub-systems (III) PX • Low Voltage: - 4 Wiener PL500F boxes (located in the cavern) • - 20 LV modules • (single channel, 5V/50A) • - Voltage Regulators: • - new location • - smaller number • - open control issues • - cables: •  see cabling scheme UX CAN bus Wiener 4 crates Wiener Ethernet Wiener 20 channels JTAG VMEJTAG ctrl V-reg. board V-reg. board V-reg. board 240 voltages 20 boards (total of 240 VR) ? SPD For each VR: • Over-Current • Inhibit ALICE DCS workshop - March 10, 2003

  9. SPD Control sub-systems (IV) ALICE DCS workshop - March 10, 2003

  10. Prototyping activities (I) Test station setup in Bari lab: (in collaboration with Antonio Dalessandro, Leonid Vinogradov) • PC with Win2K devoted to SPD control developments • PVSS2 and Framework 1.2 software installed HV control sector: • CAEN OPC Server 2.0 installed and configured on same PC • CAEN SY1527 equipped with A1519 board (12 HV channels) ALICE DCS workshop - March 10, 2003

  11. Framework selection of SY1527 with 1 HV board Prototyping activities (II) PVSS2 Framework CAEN OPC Server CAEN SY1527 HV board: A1519 ALICE DCS workshop - March 10, 2003

  12. Hierarchical structure Prototyping activities (III) SPD HV-LV preliminary control panel ALICE DCS workshop - March 10, 2003

  13. Prototyping activities (IV) Example of monitoring panels for 12 HV channels (1 half-sector) ALICE DCS workshop - March 10, 2003

  14. Prototyping activities (V) LV control sector: • WIENER PL6021 PS equipped with Kvaser PCIcan-Q card • Kvaser card drivers installed and tested (OK) • CANbus tested (OK) • Wiener OPC Server not available • SLiC.OPC Server working with Applicom OPC Client • still problems using PVSS OPC Client  investigating with IT/CO people (open issue) ALICE DCS workshop - March 10, 2003
