    keyword=shift summary

    00:00 Shift begin
    run # left 1283/ right 2155 Optics run
    00:40 unplugged the DAQ SYNC cables
    00:52 waiting for the Right dipole to settle to p=1.0963
    before starting optics runs.

    00:56 Changing the left arm momentum to p = 1.00 GeV
    to cut the elastic from the acceptance.
    Calibration run

    01:14 right arm run # 20156 Optics 1M events Collimator Open
    01:34 right arm run # 20157 Optics 1M events -Seive

    01:49 Changing right arm momentum to 1.1292 (+3%) Seive in
    02:32 start run # 20158--- 1 M

    02:32 Changing left arm momentum to p=1.0963 (0%) Seive in
    02:44 Optics with Sieve in run# 1292 1M events

    3:13 run # 1293 Leftarm (0%) without Sieve p=1.0963
    run # 20160 Rightarm (3%) without Sieve p = 1.1292 1M.

    3:30 Changing momentum for the left and the right arm
    Left arm p = 1.1292 (+3%)
    Right arm p = 1.1128 (+1.5%)
    Collimator open on both arms
    Left arm run # 1294 (High Voltages for Cherenkov changed to 2000V)
    Right arm run # 20161 600,000 events

    3:58 Left arm run # 1295 (Cherenkov voltages at 2000V)

    4:02 MCC called, No beam for few minutes problem with RF.

    04:11 Sieves in both arms. Beam back at 20 micro Amps
    Left arm run # 1296 + run 1297 -- 0.5 M + 0.5 M events
    Right arm run # 20162 + run 20163 -- 0.5 M + 0.5 M events

    04:47 Changed momenta on both arms/ Sieve Slits still in
    Left Arm p = 1.1128 --> run # 1298 -- 1 M events

    05:25 Right Arm p = 1.0799 --> run # 20164 1 M events


    5:25 Collimator open in left arm
    Left arm p = 1.1128 --> 1299 1 M events

    5:38 Collimator open in both arms
    Right arm p = 1.0799 -->run# 20165 ---> 1 M
    Left arm p = 1.0799 --> run# 1300 ---> 1M events

    Sieve slit in on left spectrometer.
    Left arm p = 1.0799 --> run # 1301 --> 1 M events

    Collimator out
    Right arm p = 1.06342 --->run # 20166 ---> 1 M events

    Collimator in/ Left arm p =1.06342 ----> run # 1302 ---> 1 M.

    6:34 Right arm collimator in p= 1.06342 -->run # 20167--> 1M
    6:38 Left arm collimator out p =1.0634-->run # 1303 --> 1M

    6:49 Optics studies done.
    Started the calibration of NaI on the left arm and moving the right arm to 60 deg.

    07:46 Right arm angle set to 59.995 deg and
    p= 1.06196 GeV/c, Raster on
    Left arm p = 0.500 GeV/c for calibration
