SL: Herbert Breuer
Target: Mat Muether
Guests: Maud Versteegen
Highlights
- Normal polarity running, random matrix, multiplicity 2,
production at 17 uA
- get Cerenkov SPE amplitudes, decide to modify HV on 4 channels
- one Cerenkov Mult=3 run
Time-line
- beam current reading today 16.8 instead of 17.1 uA; leave as is
- 01:55 increase HVs on Cerenkov o3-4, o5-3, o4-1, o8-2, after run
34753
- smooth running
