[BLAST_SHIFTS] Blast daily meeting 07/07/04

Hello,
I am the run coordinator for this week. The plan is to measure polarized
D2 with the new storage cell. Tomorrow I will come in later but I will be
reachable by phone. Below a summary of the experiment status

_ abs was regenerated (twice?) but pol data taken only starting today.
  Last night's data mostly empty target or junk.

_ CCR returned the beam to optimize Wch scaler rates. Presently running
  with a ~20 % deadtime at the top of the fill (125-130 mA)

_ DAQ status: please see yesterday's note.
  From runs 8640-8642 overnight we lose 350/45212 (0.7%) of the right-tof
  tdc in trigger 1. At the same time, we lost no l-tof tdc's. Please keep
  monitoring the situation

_ Please remember to crunch all data we put on "tape"

_ Please keep the runlist-d2.3 "readable". Too many runs are labelled
  "JUNK" when actually they are

        a) empty files or never started (the 9th run jinx)
        b) the data is fine, the roc dies before the 250 k mark
        c) lrn crashes on a certain event (data is still fine).
        d) the run is indeed junk, some detectors or the bad is bad or the
           configuration/trigger is wrong

   please try to be more informative. Runs of type b) or c) can be
   recovered
