The gas bottle was empty. Tino replaced
the previous old bottle with 50 bar gas left.
Yuri is getting new gas bottles.
Yuri got a new gas bottle. We repalced
the the new gas bottle. There is 200
bar gas left now.
The old gas bottle with 50 bar gas
left was kept inside ESR.
The empty gas bottle was removed from
ESR.
The outlet volve was decreased by 30 degree.
Since the value is almost 0, we can not read the value of outlet volve. |

Hi everybody,
is there now much more rate on the detectors?
Perhaps it helps to turn down the bias for a while and to take the detectors out of the beam, by pulling the pocket out?
And then see if the leakage current comes down again.
good luck, Thomas

Ragan | Detectors | Bias Voltage for Si-pads |
The limit of the leakage current for all Si pads was increased from 1500 nA to 5000nA and
leakage current was recorded for different Bias Voltages (32V, 35V, 40V, 45V, 50V, 55V
and 60V).
Since, I_leakage remains < 3 uA for 60 V, it is decided to increase the Bias Voltage for
all the Si-pads from 32 V to 60 V.
For DSSD and CsI, bias voltages remains same (-50V and -160V respectively). |
