We continued taking cerenkov rates as a function of threshold voltage (DEdgedisc and
REdgedisc from the trigger gui). Each setting contains > 2 millions events spread over ~6 runs. To take up space the results
are:
Field Off, CC Voltages: CC_TOF_1300.sql, Target:1 sccm
CC Rates(kHz)/I(mA)
------------------------------------------------------------------------------
CC-ThV(mV) L0 L1 L2
L3 R0 R1 R2 R3
25 138/84.3 160/81.6 51/80 17/79
288/78 99/76 95/75 26./74
35 97.2/80 121/80 36/80 8.5/80
193/80 67/80 76/80 21/80
45 94.1/80 109/80 24.6/80 4.2/80
155/80 44/80 63.5/80 16.4/80
65 63.1/79 79.8/79 9.6/79 0.8/80
109/80 17.5/79 39.6/79 7.5/79
85 40.6/80 59.3/80 3.4/80 0.4/80
84/80 7.4/80 23.0/80 3.4/80
The next step is to take the same data with the cerenkov voltages
increased by 10%, therefore a CC_TOF_1300.sql was copied over to
CC_TOF_1300_10percent.sql and modified accordingly. Recall that to
download the new hv setting one does the following:
1.) exit hvdaemon
2.) in ~blast/commis/hv on dblast07,
type:
a.) |commis/hv> mysql
b.) |mysql> drop database BlastTest;
c.) |mysql> exit
d |commis/hv> mysql <CC_TOF_1300_10percent.sql
3) |> hvdaemon 1 2
Things are set up so that Jason and Ben can continue taking data.
