Logentry Text:
Sunday 6/12 - Monday 6/13
* Completed switchover from empty (raster calibration) target to 12C target
* Did a current scan - found reasonable running conditions at 2 nA (about 20 kHz)
* Did a raster scan - up to 8 mm offset from 0 yields no more than 6-7% occupancy in RI drift chambers in the "hot" sector. Overall, rastering with 8 mm radius doesn't raise average occupancies much beyond 4%. 
* Took production data on C overnight with these settings
* Ready to swap to NH3.
PLAN: take data on polarized NH3, do a Moller run before maintenance day tomorrow.
