    Shift started

    00:00-30
    target Pb
    Runs # 20741 (right) events (ROC1 disconnect)
    2287 (left) events 2.7 M
    00:32 ROC1&2 disconnect. Reset and restart CODA
    00:39 Move the target to LH2

    00:58-01:02
    Target LH2
    Runs # 2288 (left) events:354K
    20742(right ) events:303K
    01:03 Moving the target to 12C right

    00:12-00:38
    Target 12C right
    Runs # 2289 (left) events:360K
    20743 (right) events:424K

    01:38 Move target to Iron right

    01:45-02:08
    Target 56Fe right
    Run# 2290+2291 (left) events 43K+ 416K
    20744 (right) events 416K

    This ends the left arm production runs at 120 deg
    2:10 Moving the target to Pb
    Moving the right spectrometer to 125.303 MeV/c
    Analyzed run 2208 and decided to set the momentum of the left arm
    to 305.292 MeV/c

    3:00 Started beam scan study
    4:17 finished beam scan study and right spectrometer has settled at 125.30 MeV/c. Start production on right arm

    4:27-04:49
    Pb target
    Run # 207747 (right) events 1.3M
    2299 (left) events 484K
    Moved the target to LH2

    4:54-05:02
    target LH2
    Run # 2300 (left) events 69K
    20748 (right) events 245K

    5:06 Move target to 12 C right

    05:11-05:37
    target 12C
    Runs # 20749 (right) events 419K
    2301 (left) events 311K

    Move target to 56Fe right

    05:43-06:09
    target 56Fe
    Runs# 20750 (right) events 436K
    2302 (left) events 335K

    Changing the momentum on the right arm to 113.369 MeV/c
    to take the last data sets at 120 deg.

    6:21--6:47
    target 56Fe right
    Run # 2303 (left) events 338K

    Moved target to 12C

    6:57-07:16
    Target 12C right
    Run # 2304 (left) events 276K
    20751 (right) events 285K

    07:21-07:41
    Target 56Fe
    Run # 2305 (left) events 352K
    20752 (right) events 351K

    07:50-7:54
    Target LH2
    Run # 2306 (left) events
    20753 (right) events

    7:54 Asked for controlled access to switch the left arm polarity

    Shift Ended
