LHRS DAQ

NOTES ::::

00:40 ==== BB HV tripped due to beam trip (2112)

00:44 ==== LHRS P_o changed to 0.6 GeV/c

2:00 === NMR done ( polarization ~ 63.9% )

2:25 to 3:05 == Cycling of Q2 and Q3 ( It took a lot of time to cycle Q3. and then the dipole took also sometime to stabilize.)

3:05==LHRS P_o changed to 1.34 GeV/c

4:35==LHRS P_o changed to 1.12 GeV/c

5:50 == LHRS P_o changed to 0.80 GeV/c

LHRS DAQ crashed. ROC 3 , ROC 4 and TS11 were rebooted

7:00 == LHRS P_o changed to 0.60 GeV/c

There were quite a few number of BB HV trips.

Junk Runs == 20634,20635,20637,20639,20640,20646,2177
