Test Report from Tuesday 26.06.2007

• RB.A78
  • PIC2 - Test completed OK
  • During the whole day, the noise read by the bus-bar quench detector of the circuit tripped several times. The source of the noise (period of about 20 minutes) has not been identified yet.
  • PLI1 (760A)
    • PLI1.1 - Current cycle - Test OK
    • PLI1.2 - Energy extraction discharge (quench to a current lead) - Test OK
    • PLI1.3 - Powering Failure from PC - Test OK

• RQ5.L8: Commissioned up to PLI3 using the sequencer - Tests OK

• 60A closed orbit correctors - P2N completed for one corrector using new automated procedure

• RQF.A78 - Type test completed - Test OK

• 600A correctors
  • RCO.A78 and RQT12.L8B1 - PCS completed - Test OK

Test Plan for Wednesday 27.06.2007

• Show goes from 7:00 to 22:00

• RB.A78
  • PLI1.4 - FPA from PIC
  • PLI1.5 - Quench heater discharge on A28.R7
  • 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 LBBRA.13L8 (magnet 3002) and LBARA.13R7 (magnet 1054)

• RQF.A78 and RQD.A78 (once RB.A78 tests are completed)
  • • RQF and RQD ramped up together to 6500A. Quench on 15L8
    • RQF and RQD ramped up together to 6500A. Quadruple quench 20L8, 19L8, 19R7 and 22R7 .

• Simmultaneous powering of RQF.A78, RQD.A78 and RB.A78.

• 600A Correctors - More circuits will be released in the afternoon by QPS for PCS tests

• 60A Closed Orbit Correctors
  • P2N will continue
  • Type tests for some converters in the evening after quenches in the main circuits

• Matching Section
  • Reproduction of the quench event of May 31st
  • Last commissioning step of RQ5.L8 via the sequencer

• AB/PO (David) will prepare a list of the activities to be carried out in the conveters already commissioned before the warm-up
