Konstantin | DAQ | Phase shift in DAQ1 | In the SetParameters.C file is a parameter
called fPar->piPhaseOffset. It was shifted
from 100 to 50 in order to see ion bunches |

Carsten | Detectors | PMT behaviour - noise / PMT voltages / CFD Threshholds / CAEN Power supply (broken channel resetted) | In position North there is still the "old"
9423B PMT that draws quite some current.
On this detector threre is also some quite |
