All Particle detector values are after the respective number of scans.
AT 1700 Bernd came in since we couldn't properly accumulate. Bernd adjusted the deceleration HF and slightly changed the extraction kicker from 1.9mrad to 1.7 mrad. High intensity of 229/89.
At 19:35 again problems with transmission SIS -> ESR. Put the Kciker (GTE3Mu1/HIKICK) back to 1.9 mrad (orignal value). |
