keyword=target boiling run fact sheet -- for lumi crew
Below is the lumi configuration during the target boiling test.
First past of the studies were done using G0 beam. Using the HV Mark determined
last night.
time Run# lumi w/ preamp I(uA) raster (mm^2) fact
10:13 14684 lumi1 15 2X2 HV tripped
14685 lumi1 0 lumi pedestal
10:44 14686 lumi1 15 2X2 12K events
10:55 14687 lumi1 15 2X2 1st 20 min
11:20 14687 lumi2 15 2X2 beam off shortly after
11:25 14688 pedestal 0 lumi1-3 were cycled
11:31 14689 lumi2 15 2X2
12:03 14690 lumi2 15 1X1
12:20 14690 A4lumi 15 1X1
12:36 14690 lumi1 15 1X1
13:18 14691 A4lumi 17 1X1
14:55 14692 A4lumi 17 0.5X0.5
15:06 14692 lumi1 17 0.5X0.5
15:21 14692 lumi2 17 0.5X0.5
Then we went to the standard CW beam and go to high current. Due to the limited
time, we decided to use LUMI2 only, since it is the most sensitive lumi we have.
Mark and I changed the HV on lumi2 so that we only saw roughly 35uA anode
current from the tube @ 33uA beam ---- so 1275V on LUMI2.
14695 lumi2 33 0.5X0.5 short
14696 lumi2 33 0.5X0.5 short
14697 lumi2 33 0.5X0.5 short
14698 lumi2 junk, ROC3 died
14699 lumi2 33 2X2
14700 lumi2 33 2X2
14701 lumi2 33 pedestal, cycle through lumi 1-6
Left A4LUMI connected with the preamp. All HVs off.
