keyword=Shift Summary
00:00 Shift begins
Jack and Brad access to the hall to try a fix on the dipole.
Bad news! No luck the fixing need to wait for tomorrow.
01:00
Asked for beam permit.
Moved the target from He to empty.
Asked for a harp scan and logged the results.
RMS in u 0.448mm in v 0.209mm
01:12
Asked MCC to make the size less than 0.2mm in both directions.
01:27
Logged new Harp scan results both for A and B sizes < 0.2mm
Moved target to Beam right Carbon
01:32 Spot_L run #1560 Shape of raster not acceptable.
MCC working on the raster size.
2:12 After few trials we settled on 2x2.5 mm^2 at the target
that corresponds to MCC 2.5x4 settings.
2:17 Momentum = 412.636 MeV/c

06:30 change mometum back to 358.708 MeV to take the Pb target
7:00 Change to New momentum to 311.828 MeV/c
run # 1546 He
run # 1547 Loop 2 Pb by mistake for a very short time
run # 1548 Loop 3 Pb
