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.
