  3. Functionality of the HVDS A Master/Slave HV distribution system will deliver the required voltages to the TRD readout chambers: Drift HV: 540 ch. ~ -2.5 kV 170μA/ch (max)ΔΑ/Α ~ 40nA/ch Anode HV: 540 ch. ~ +1.6 kV 7 μΑ/ch (max) ΔΑ/Α~ 2nA/ch

  4. Concept of connecting the High Voltage Distribution System to DCS-Bord • Layout of a Rack: • Layout of a Crate: • Layout of a Module:

  5. Architecture of the CAN network inside one rack: Module 0 Card 0 Card 1 Card 2 Card 3 Module 1 (Internal architecture similar to module 0) Card 4 Module 2 (Internal architecture similar to module 0) Crate 1 (Internal architecture similar to crate 0) DCS Board 1 (Optional) DCS Board 0 Crate 0

  6. Control Parameters • HVDS (card) status set, read • card temperature read, alarm • card input voltage read • channel status set, read • desired voltage/current set, read • actual voltage/current read • max allowed voltage/current set, read • max voltage/current is exceeded read, alarm • start ramping up/down set • stop ramping set

  7. ramp speed up/down set, read • max allowed ramp speed set, read • time of periodically trans. V, Ion normal operation set, read • time of periodically trans. V, I while ramping set, read • action on trip (kill, enable, disable) set • order all actual data for one channel (status messages) set

  8. Outlook • Update the TRD – URD. • Implement the FSM to continue the development of the HVDS control according to the standard HV state diagram. hierarchy : device and detector alarms : different alarm severity conditions are foreseen

  9. Outlook (cont.) • Integrate the HVDS control in the TRD control system.
