ge4:00 Carbon target, 5uA, raster4x4, confirm raster size
4:10 Carbon target, 5uA, raster2x2, confirm raster size
4:19 Carbon target, 5uA, raster6x6, confirm raster size
4:31 Production cell, 2uA, raster2x2, T3=171
4:37 Production cell, 2uA, raster6x6, T3=177
4:44 Ready to production, 10uA, raster4x4, but RHRS has high deadtime, Brayan is trying to fix.
6:05 Controlled access, Ramesh down to the hall to fix crazy RHRS T8.
7:00 Controlled access finished, deadtime of RHRS around 15%.
7:19 Carbon target, 5uA, raster4x4, confirm raster size
7:27 Production cell, 2uA, raster2x2, T3=175
7:30 Production cell, 2uA, raster6x6, T3=185
7:44 Ready to production, 10uA, raster4x4, but Lumi DAQ is not working, trying to fix.
8:05 Take run#1881 and run#20788 without Lumi.
8:26 Lumi DAQ is back, take production run#1882 and run#20789 with Lumi.
8;15 move target to reference cell, fill H2 into the cell, 135psig.
8:19 2uA, 4x4 check raster size.
8:24 10uA, take reference cell(H2) 1M events production run#1884 and run#20791, beam down 6 minutes.
10:07 10uA, take reference cell(H2) 1M events production run#1885 and run#20792.
10:52 2uA, 3He target, check spot++
11:05 beam down, MCC said that CHL is down due to a lighting, will take at least 4 hours to fix.
Production runs:
LHRS/RHRS
1881/20788(without Lumi)
1882/20789
1884/20791(reference cell: H2)
1885/20792(reference cell: H2)
