Program

Postponed from day shift 9/8
...
For all following activities keep CU at 0 angle, direct beam in center of tower 3. to 11/8 swing because of non availability of beam on 9/8 and 10/8

e | 1 | S2+S4+NOSh+NOS3+C1+C2 | 200K 100K | 1 GeV photon tagged | magnet on at scaled current (240A - CHECK current-BL calibration); collect runs of 25K evts each | ||||||
e | 1 1 | S2+NOSh+C1+C2+Sback | 10K | test to redefine full-brem photon trigger to maximize efficiency | add Sback after tagger and in trigger, take data with no AD | e | 1 | S2+NOSh+C1+C2 | 10k | test to get full-brem+AD | read sync AD but full-brem trigger; test data readout rate and synchronization |
e | 1 | S2+NOSh+C1+C2(Sback?) |
| full brem at 1GeV | collect 2.4 M evts in 250K runs | ||||||
