Entry number 334545

The first half of day shift was spent attempting a BCM calibration.  This was
ultimately aborted due to a mismatch between the Faraday cup and 0L02 at the
injector.  That calibration was corrected in early swing shift:

The BCM calibration for Hall A will need to be rescheduled for later in the
week.

The rest of day shift was used by MCC experts to optimize the injector and
accelerator transport tune to maximize beam quality to all three Halls.  We
took a brief controlled access at 4:30pm to refill the Moller dewar and
make a couple of other adjustments in the Hall.


UPCOMING SHIFTS:

When we come back up (should be soon) we will spend a few hours
optimizing the beam through Compton region.

The rest of SWING and OWL will be spent taking data on the LH2 and carbon
targets.  Items that should be completed include

- Finish vertex calibration data taking
  * 50uA beam
  * Raster OFF
  * Multi-foil carbon target
  * take at least 200K events
  * quasi-elastic kinematics: p0=3.327 GeV/c

- TEST of the Arc energy scanners should be done when Arun calls in this
  evening (should be a 10 minute test plan to confirm the hardware is working
  properly).

- Continue with DAQ shakedown and elastics data-taking off LH2 target


LONGER TERM ITEMS:

 * Moller run, possible mini-spin dance?
 * Arc energy measurement
    - should probably be AFTER the spin-dance in case there are minor energy
      tweaks to maximize polarization to Halls A and C
 * HRS polarity flip when calorimeter is ready
 * HRS polarity flip back after roughly 3 shifts of data taking
