  1. Serguei SadovskyALICE controls workshop15 of March 2004 PHOS DCS status Serguei Sadovsky

  2. ALTRO electronics has been chosen as the base line of the PHOS FEE The design of the ALTRO FEE card has been finished All control circuits on the FEE card have been implemented All HV and LV values have been specified The HV and LV power supplies have been chosen The DCS for the PHOS FEE cards is similar to that used in TPC PHOS DCS status Serguei Sadovsky

  3. The APD HV bias regulation for each PHOS channel has been implemented on the PHOS FEE cards by means of 10 bits DAC The PHOS DCS can be used only for the HV setting (3584 channels/PHOS Module) For control of the HV setting the LED monitoring signal positions will be used Thus an interface between DAQ and DCS system has to be foreseen Preliminary design of the PHOS cooling and thermo-stabilization system has been presented PHOS DCS status (continue) Serguei Sadovsky

  4. PHOS-Ecal DCS (5 modules) Serguei Sadovsky

  5. Answers: PHOS HV power supplies……….Iseq EHQ80, 5 PS PHOS HV ……………………… can be moved to CR Number of PHOS HV channels …5x8+8(spare) PHOS LV power supplies……….Wiener PL500,5+1PS Number of PHOS LV channels….5x6+2(spare), power 5x6+2(spare), sense PHOS RCU ……...…..…………..5x4 PHOS-Ecal DCS (for 5 modules) Serguei Sadovsky

  6. LED LV power supply……. PS type ??, 1+1 PS Connection: ….Rack C09 –> PHOS trigger crate Number of LED LV channels……..1+1 (power) 1+1 (sense) PHOS-LED DCS power supplies (for 5 modules) Serguei Sadovsky

  7. PHOS temperature monitoring and thermo-stabilization system (for 5 modules) Cooling system function: Measurements of the temperature: • temperature monitoring of cooling liquid ……. 4 channels • compressor control....1 channel • pump control……….1 channel • surveillance over the cooling liquid level…1 channel • heater control ………1 channel • temperature distribution in the crystalmatrix …………..…… 5x60 channels • temperature insidethe “FEE” volumes ………………..5x2 channels • temperature in the experimental hall ………………………..1 channel Serguei Sadovsky

  8. PHOS-CPV DCS (5 modules) Serguei Sadovsky

  9. Answers: CPV HV power supplies ……...CAEN SY1527, 2 PS CPV HV ……………………….can be moved to CR Number of CPV HV channels …5x4+2(spare) CPV LV power supplies………Wiener PL500,5+1PS? Number of CPV LV channels…5x8 CPV on detector electronics …..5x5 I/O device? PHOS-CPV DCS (for 5 modules) Serguei Sadovsky

  10. status of cooling liquid level status of the pump status of the cooling machine Interlocks of the PHOS temperature monitoring and thermo-stabilization system “Hardwired” internal interlocks: “Hardwired” cross-system interlocks: • status of the crystal matrix temperature • status of the FEE temperature • status of the cooling system Serguei Sadovsky

  11. status of the LV power supply currents status of the LV power supply temperatures status of the HV power supply currents status of the HV power supply temperature Interlocks of the PHOS HV & LV Power Supplies “Hardwired” internal interlocks: Serguei Sadovsky

  12. status of the CPV LV power supply currents status of the CPV LV power supply temperatures status of the CPV HV power supply currents status of the CPV HV power supply temperature status Ar & CO2 pressure status of the CPV gas mixture Interlocks of the CPV HV & LV Power Supplies, Gas system “Hardwired” internal interlocks: Serguei Sadovsky

  13. CONCLUSION Definite progress with the PHOS module DCS since the last ALICE DCS meeting Serguei Sadovsky
