turn down the hv and pull out the detector.

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

Wed Apr 1 01:05:36 2020, ruijiu, Detectors, detector position fixed at 60 mm
|
The detector cable was disconnected . We entered and reconnected the cable. |

Thu Apr 2 12:52:25 2020, ruijiu, General, setup FRS with 2 g/cm2 degrader.
|
Yuri sets up FRS with 2 g/cm2 degrader (previous one is 1 g/cm2). The ESR is not changed. The contamination should be less now. |

Mon Apr 6 14:17:54 2020, Yuri, Shahab, Runs, FRS valves
|
We saw reduction in ESR beam life. It turned out that FRS has opened valves and venting caused us reduction of the quality of vacuum in ESR leading to beam loss. We manged to closed GEE5VV so that now beam is stable somehow.
how could you guys!!!!
arrrrgggggggg!!!!!!! |
