Hall work¶

• DC report
  • SSU/FC ramp went well
    • Yay. But need to be careful that run settings have been tested before hand.
  • SSD diode test report
    • SSD ramping down now. A bit of noise was seen but not the amount we've been seeing. However there was still unacceptable noise.
    • We are going to test SSU tomorrow. The noise problem has not been cured.
  • DS compressor progress
    • Leak has not been found, but contamination continues rising.
    • Will need to strip down the compressor (weeks work), then cooling the DS down will take more time.
  • Aircon in RR2 now keeping rack temperatures beneath 30C.
    • Racks are now cool enough. Area outside the control room is now a sauna.
  • Water to conventional magnets.
    • A leak was sprung in the trench when we tried to put conventional magnet water supply on. This was a reflection of partial control of
      the pumps in the trench which are on full power and putting too much pressure in the system. We have a route out of the problem. Water to
      conventional magnets are off until Thursday at best. John wants to get into DSA to shut a valve to do the work and then needs to open it again.
  • MICE hall tour for FFAG workshop, Wednesday 7th September
    • Paolo/Durga giving tours
  • Other:
    • Need to get downstream tracker cooling ASAP
      • The RGA testing on the tracker will start tomorrow.
    • Cover for SS QP cables in RR2
      • Cable covers need to be installed.
    • UPS to be installed in RR1

• Shandor arrives tomorrow, Alan arrives on Thursday, Shandor goes on Tuesday.
  • Get in touch with Yordan and say that we will be doing the expert startup
  • Need to tell ISIS people when we do a beam tune.

• Plans for the following week

Operations and data-taking¶

• Data-taking
  • Start of data-taking has been pushed back to 18 or 19 September (from the 13th).
  • Will need to make a decision once the DS work has been carried out on how/when we run.
  • We do need an expert run : this has been discussed and planned for Sept 12 (pulsers) and Sept 13 (beam).
  • We will need to do beam tuning as usual.
• Maintenance plans
  • Need to compile a list of "regular" checks needed in the Hall during run periods
  • Need to decide on a regular maintenance slot (for e.g. checking temporary neutron monitor)
    • Wednesday morning?
• AOB
  • New DC phone number is on the expert list

• DONM : 13th September in CR12
