[Halld] Run Coordinator summary for Nov 1-7

[Naomi Jarvis]

Dear Collaborators,

Here is a brief summary of progress last week (Nov 1-7):

We were scheduled to receive 161 hours of beam and received 104, with 98 of
those acceptable.  The largest period of downtime was caused by a vacuum
pump failing in the photon beamline in the tagger hall.  It has been
replaced.

Special tasks completed during the week include:

CompCal installation continued during scheduled downtimes, controls were
tested and nitrogen flow connected;
Test run with coherent Bremsstrahlung peak at 7GeV instead of the usual
9GeV, and low beam current, in preparation for low photon energy studies;
Test run with the Pair Spectrometer at half its usual field, also in
preparation for low photon energy studies;
TAC run with low Pair Spectrometer field setting was in progress on
Wednesday when my week as RC ended.

During the week we collected a total of 12.7 E9 production triggers.

Best regards,

Naomi.
