Comments: 00:00 NMR: target polarization 12 % 0:09 began run on empty target (collimators out, Ep=1.607 GeV/c) 00:50 High deadtime when the beam is well tuned and low when the beam is off by X=-0.5 (offset on the target position ?) -->we had to decrease the raster size 1:45 Q1 hadron tripped 2:04 coda crashed, then began N2 run at 5 atm 3:20 NMR measurement 22 % target polarization 4:19 Q1 hadron tripped 3:35 empty cell run, collimators in, Ep=1.484 GeV/c 4:45 empty cell run, collimators out, Ep=1.484 GeV/c 5:16 coda crashed (deadtime at 100 %, rate at 0 Hz and no update of the data mon. and the number of events when we started a new run. 5:45 NMR : 26 % target polarization 5:56 began runs on N2 at 5 atm. 6:44 lost Q1 hadron, end the N2 run 7:00 NMR : 27.6 % target polarization. As the polarization is high enough we decide to change the runplan and come back to 3He production runs 7:10 begin 3He production runs at Ep=1.484, E=1.719, Theta=15.5 degree
