    16:00 Shift starts
    There is a controlled access where Jack is down working on the RHRS dipole

    17:16 Jack and Aidan back from the Hall.
    Cycling Q3 left
    Ramping Q1 Right
    Ramping the R HRS dipole

    Pengjia and Alex take a Harp scans moving the beam spot on the BeO target. Summary below

    20:25 requested controlled access for Bob Michael to work on the helicity checks.

    20:30 in the mean time still rampimg R HRS dipole
    20:45 after Radcon finiched it's check Bob went to the hall
    22:20 Bob is back from the Hall. See halog for his report
    Dipole for R HRS is very close to nominal current value.

    22:25 Called MCC to restore beam on BeO target
    BPM A (-1.5, 0)
    BPM B (-3.5, 2)

    Checked spot size and 8x6 corresponds to 3x3mm
    Asked MCC to put it at 6x4 wich gave us 2x2 mm

    22:50 Moving to LD2 4 cm Deuteron Elastic runs.

    23:05 run # 1603 at 5 then 10 then 20 uA
    23:15 run # 1604 at 20 uA 251K
    23:38 run # 1605 at 40 uA 284K

    Moved target to LD2 15 cm
    24:00 run # 1606 at 20 uA
    24:00 Shift ends
