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.

Thu Oct 1 22:20:03 2020, Jan, DAQ, final unpacker config
|
We identified an issue with randomly missing adc channels in all lmd-files before run 0273.
This led to errors in the unpacking process.

Attached is a list of all set values for the 5 MSCF shaper modules.
This was done prior to run0251, which served as a final benchmark for those settings.

The frequency of the clock used as reference in scaler channel 13 has been measured precisely.
In contrast to what was expected (1.5MHz precisely), it is:
