Kin G; LHRS (for electrons) momentum setting: 1.2 GeV/c, angle:45 deg
Beam energy: 5.892 GeV.
16:00 Shift starts with no beam.
N2 reference cell data for this kinematics were already taken during Day-shift
17:35 Beam is back. Asked for harp scan (with 5 uA beam with raster off). Harp results look good (halog entries: ). Perform BeO target raster check. Looks good. Go for 3He target for raster scan first.
17:57 One of the beamline dipoles tripped off, beam will be off for about 15 minutes.
18:20 ARC 4 magnet tripped off, experts contacted, no time estimate for when the beam will be back.
00:00 Shift ends with no beam.
