Powering of sector 78 - Report of 12.06.2007

Test Report of Tuesday 12.06.2007

  • ElQA
    • Tests in MBA line will continue tomorrow till noon.

  • RD2.L8:
    • Ramped to 200A. Quench heater fired. Post-mortem data acquired properly. Test OK
    • Ramped to 1kA. Quench heater fired. Post-mortem data does not arrive properly to the viewer. Test NOT OK
    • Second ramp to 1kA. Quench heater fired. Post-mortem data created is corrupted: the data is an exact copy of the one created in the previous with no new data. The QPS controller needs to be restarted. Test NOT OK

  • 600A QPS Controllers:
    • RQ6.R7B1 and RQ6.R7B2 are now ready for powering. Next step: PCS.4 (plateau at 200A)
    • The available 600A correctors in the DFBAO are released by AT/MEL for powering.

  • Sequencer Test 600A sequence - Completed using RQTL12.L8B2

  • RQ6.R7:
    • Different ramp rate applied (up to nominal ramp rate of 1.3 A/s). Current cycles between +10A -10A.
    • Noise level: 20 mV
    • Circuit ramped at 5 A/s: trip at 20A. Test NOT OK.
