We will ramp up the current on the thick lead PREX target.
Started at 03:24 with 20 uA.
Check target with run 3582 now
See fig 1 & 2. Target is intact and no scraping.
BPMB at -0.2 and 0.8. Will move closer to (0,0) after this run.
Trigger rates are
T1 = 29.2 kHz
T2 = 56 Hz (S0 out of way)
T3 = 0
T4 = 310
Scint rates are 10 to 20 kHz.
I notice that also the L-HRS has 10+ kHz rates. Increase
L-HRS momentum setting to 3.0 GeV.
