Powering Tests Sector 7-8 - Report 22.06.2007

Test Report of Friday 22.06.2007

  • RB.A78
    • PIC1 - Completed OK after a the solution of an adjustment problem in the current loop controller of the QPS (few mA too low).
    • Connection of the 60A conveter to the RB circuit in the UA83 side. The TF measurements could not be completed because the converter noise made the bus-bar quench detector trip everytime it was switched on. The detection threshold will be increased on Monday.
    • The time out preventing from closing the switches too early after a switch opening has been lowered in order to speed the tests up.

  • RQF.A78
    • PLI1 (760A) completed - Test OK
    • PLI2 (2000A) completed - Test OK
    • PLI3.1 (current cycle up to 6500A) completed - Test OK

  • 60 Closed Orbit Correctors
    • PCC carried out in one circuit.
    • All the circuits released by ElQA have been connected to the power converter.

  • AB/PO current stability measurements in RD2.L8 - Completed

  • Empty of DFBMA and Q4/D2 started in the evening

Test Plan for Monday 25.06.2007

  • RB.A78
    • Provisional correction of the detection threshold of the bus-bar quench detector in order to allow TF measurement with the 60A converter.
    • TF measurement
    • Desconnection of the 60A converter and final connection of the RB converter to the circuit; PCC tests
    • Set detection threshold back to operation value
    • PIC2
    • PLI1 (760A)
      • PLI1.1 - Current cycle
      • PLI1.2 - Energy extraction discharge (quench to a current lead)
      • PLI1.3 - Powering Failure from PC
      • PLI1.4 - FPA from PIC
      • PLI1.5 - Quench heater discharge on a selected magnet
    • PLI2 (2000A)
      • PLI2.1 - Current cycle
      • PLI2.2 - Energy extraction discharge (quench to a current lead)
      • PLI2.2b - SPA from PIC
      • PLI2.3 - Quench heater discharge on a selected magnet

  • RQF.A78 (6500A)
    • PLI3.2 - Energy extraction discharge
    • PLI3.3 - Quench heater discharge on 12L8 SSS

  • 600A Correctors
    • Software upgrade by QPS
    • PCS tests on the circuits: RQT12.L8B1, RQS.L8B1, RCO.A78B1

  • DFBMA will me refilled in the afternoon

  • 60A Closed Orbit Correctors: PCC and P2N whenever possible
