October 26 , special meeting to discuss Bernd's task list

Present:Gene, Bernd, Joe, Jan, Rosi,Justin, Ilya
Minutes

Bernd reported from the private meeting w/ Jerome. There is general good, common understanding of priorities.
From the list of 'red items' on Bernd's list 2 are problematic:

  • implementing deconvolution code would take months in real time , during meeting we have agreed to descope this item
  • commissioning of MC filter. Jerome plans to personally review the code, not sure when it may happen. Jan made suggestion to delegate this task.

Rosi confirmed the T0 fix did not helped in restoring CMB tracks in PPV. She will try to investigate it further, but asked for new ideas. So far nothing is wrong. It was not confirmed CMB tracks are missing also for M-C events. This item has no ETA.

Joe & Matt realized the mip-less towers w/ good slope have either wide pedestal, or low gain, or unstable HV, or all of the above (the spectra and detailed rapport will be posted). All such towers will have offline gains determined from the slopes (are restored). Now we will have only ~100 dead towers in BTOW. List of those will be posted on emc2-hn , so there is a record, perhaps some can be repaired before the run. No evidence of elusive towers with mixed fibers.
