Progress since September 9th• Sector 12:

• QPS IST finishing. The first sector took longer than expected, and its experiment shows that 3 steps are needed for the full

commissioning of the nQPS system. But the results are there.

• Powering tests phase 2 in progress

• Sector 23• ELQA at cold finished• nPST racks installed, the tests for 2kA will follow the 6kA tests in sector 78 Powering phase 2 of the mains will start in wk. 43 (2 wks. of delay w.r.t September 9th )

• Sector 34• DSLC filling this week-end, boil-off will be done next week, • 2 wks. of delay w.r.t September 9th (Logistic)

• Sector 45• ELQA at cold finishing, some delays due to DFBA consolidation (valves and filter)• Powering test, pahse 1 just starting• 1.5 wks. of delay w.r.t September 9th

Progress since September 9th• Sector 56:

• ELQA at cold finished• Powering tests phase 2 will start this week. • 2 wks. of delay w.r.t September 9th Is this coming from the DFBA consolidation ???

• Sector 67• Boil-off in progress- 2 wks. of delay w.r.t September 9th (Logistic)

• Sector 78• ELQA at cold finished• nQPS tests at 2kA in progress• Powering tests phase 2 in progress• 2 wks. of delay w.r.t September 9th Is this coming from the DFBA consolidation ???

• Sector 81• ELQA at cold in progress, some delays due to DFBA consolidation• 1 wk. of delay w.r.t September 9th

Schedule outcomes

• Powering phase 2 – durations (number of shifts): the experiment of

sector 12 shows that the number of shifts was overestimated,

– but the experiment of sector 12 shows that about two weeks are needed to commission the system at 2kA & 6kA (part of the powering tests).

Remaining activities

• Doors: PM18 and SPS• Floor painting• Smoothing and beam vacuum chamber alignment in sector 34• Test of UPS batteries

All the machine areas have been cleaned again, all the “alone” materials have been removed. So please keep the areas clean.

Conclusion

• Machine cold in wk.41• Powering tests phase 2– Experiment of the first sector was very good– Durations (in term of shifts) were overestimated– New tests to be included for the nQPS– End of powering tests phase 2 = wk.47 (+1.5wks)
