Owl shift summary:
Shift workers: J. P. Chen (SL), X, Yan (TO)

0:00 no beam: RSEP8A and A slit problems.
1:20 MCC started beam tuning.
2:00 pulsed beam then CW beam, Compton rate very high (MHz).
3:00 After pathlength adjustment, Compton rates still high (~500KHz).
Decided to go straight through.
4:20-4:40 harp scan, OTR
4:40 started position scan with Empty target
5:05 check raster size
5:15 Pb target position scan
6:20 production
6:25 MCC has problem with magnet shunt power. 
7:11 beam back, resume production
7:25, beam off, ioc trip.
7:56, beam back.

E0=3680 MeV, both angle at 15 degree.

Left P=3557.302 MeV, Right P=3092.526 MeV
