  37   Wed May 11 03:17:14 2022 Patrick, Volker, Guy RunsStart laser scanning
Runs of the night shift. The wavelength range is 601.95 - 601.735 nm.
We started the wavemeter python script on atppc023 located in Desktop/wavemeter_Bi.
We changed the wavelength range in go4 to the actual scan range.

Questions:
There are many other masses/isotopes/etc. visible in the Shottky spectrum. Is this wanted?
Are the vacuum gauges turned off?
Laser timing correct? +- 3 bins?

No, this is not wanted and yes, the machine is aware of the problem. The decision on Tuesday evening was to leave the ESR in that state in order to start the measurement and continue setting on Wednesday. Otherwise the night shift could not take place.

The additional isotopes are only a few percent and should contribute insignificantly to the background rate.

Tried 20 injections, got no injection into ESR, so moved back to 15. The scrapers were not moving for quiet some time, even after fixing them. The problem may have been that two ParamModi windows were opened. The injection into the SIS does not work when there are other users performing special operations with the machines.

The vacuum gauge of the e-cooler failed. It was restarted. Apparently, upon changing/fixing anything related to our accelerator pattern, the scrapers forget to move. Then they have to be disabled and enabled again in ParamModi. Also, the injection does not work very well. Either the transition from SIS to ESR fails or we are just skipped completely. After fixing the injection, again the scrapers failed as expected. We keep the scrapers out now.
