Powering Tests Sector 7-8 - 19.07.2007

Test Report from Tuesday 19.07.2007

• RQD.A78:
  • Transfer function measurements with 60A converter completed OK
  • PCC Circuit Config tests completed
  • PIC2 - All steps completed OK except:
    • Circuit discharge from power converter: switches were not rearmed after PM data generation - Test to be repeated
    • Discharge request from PIC - to be done

• RQF.A78:
  • Transfer function measurements with 60A converter completed OK
  • PCC Circuit Config tests completed
  • PIC2 - All steps completed OK up to Powering Failure test (included)

• RQ4.L8 and RD2.L8:
  • Tests 1 and 2 proposed by MPP completed but without provoking an artificial quench at the end of the second. Detection threshold still at 20mV. Still no quench. Further research to be done.

• RCO.A78B1 powered below 20A for QPS analysis. The circuit is still blocked till the new sofware is uploaded.

Test Plan for Wednesday 20.07.2007

• Resolution of cable signal/interlock swap F/D

• RQD.A78 (from the CCC):
  • Last two steps of PIC2
  • PLI1 (750A)
  • PLI2 (2000A)
  • PLI3 (6500A)

• RQF.A78 (from the CCC):
  • Complete PIC2
  • First steps of PLI1,2,3 if possible

• RB.A78
  • IST Energy extraction tests, PIC1, connection of the leads

• Matching section:
  • Type analysis of the power converters
  • Analyse boil-off data and eventually repeat a more complete boil-off
  • Waiting for new proposals from MPP
  • 120A converter on Q5 type tests
