Powering tests Sector 7-8 _ 04/07/2007

Morning shift activity.

  • RSD2.A78B2 done up to PCS4
  • RQS.A78B2 wrong polarity
  • RQS.R7B1 wrong polarity
  • RQTL10.R7B1 wrong polarity
  • RSD1.A78B1 high noise
  • RSD1.A78B2 card problems
  • RSF2.A78B1 done up to PCS2
  • RSF2.A78B2 tripped during PCS1
  • RSF1.A78B2 done up to PCS3

Performance test done on: RQS.L8B1 RCS.A78B2 RCS.A78B1

24h run stopped at 11:30.

Afternoon shift.

The following circuits have been testes up to PCS4:
  • RQS.A78B2
  • RQS.R7B1
  • RQTL10.R7B1
  • RSF1.A78B2
  • RSF2.A78B1
  • RSF2.A78B2

The following circuits are affected by a problem in a QPS card: RSF1.A78B1 RSD1.A78B1 RSD1.A78B2

RQ6.R7B1/B2 were tested but tripped due to QPS threshold. Reiner needs to increase the threshold there. In agreement with MPP, it has been decided to raise their threshold to 50 mV.

Activity for tomorrow, Thursday 5th.

  • condamnation of all coverters of point 7, to allow ElQA to start their tests there (RQ6, in DFBMH, is on the same electrical depart as other circuits of DFBAN);
  • Reiner will work on the QPS system for RSD1.A78B1/B2 and RSF1.A78B1 tomorrow morning around 9.00 (change of detection card required); as soon as he finishes, those circuits will be powered up to PCS4;
  • as soon as the three circuits above are over, condamnation of all converters of DFBAO;
  • as soon as Reiner finishes the intervention on RQ6 (probably early afternoon), the corresponding converters will be de-condamned and RQ6 powered for PCS4 (THIS HAS TO BE DONE IN ACCORDANCE WITH ElQA FOR WHAT MENTIONED ABOVE ON THE SAME ELECTRICAL DEPART!!!); the converters will be condamned again right after.

  • ElQA activity:
    • matching section to be completed;
    • RB to qualify (after disconnection by Philip Denis of leads in point 7)
    • RQF/D qualification
    • 60 A COC

    • DFBAN ready from the morning
    • DFBAO ready from the afteernoon

  • Installation of passive heating system on one 600A of DFBAN (Vincent Fontanive)

  • DFBXG.3L8 will be cold-tested tomorrow afternoon.
