    keyword=Target test: loss/temperature studies

    Target test during MD period:
    After beam off this morning at 4:30 am, Kevin did EPR loss study measurement
    and NMR loss study measurements. Then temperature study at different target
    positions with EPR.
    During day shift, I did rotation loss study measurments: all with lasers off.
    NMR (always at 0 degree), then rotating to 270 and back to 0, NMR;
    then 270 again back to 0, NMR; to 90, back 0, NMR; to 90 again, back to 0, NMR;
    to 180, back to 0, NMR; to 180 again, back to 0, NMR; to 90 back to 0 5 times, NMR. Now three lasers on to pump back for 2 hours. Next shift will do a base
    line measurement: after 2 hours pumping, turn off lasers, wait for 10 minutes,
    start NMR, then do NMRs at the same time interval as were done during rotation
    loss study.
