Esther, Alexis, Anton, Rodolfo, Carsten | DAQ | R4l-41 | We have some issues with the RIO computer
R4l-41 (DAQ1). We had to switch off completely
twice. Only then it reacted properly. Maybe |

Konstantin | Accelerator | Position of contaminants | I checked the positions of the contaminants.
Therefore, I drove the scrapers and observed
the signal at the Schottky detector

Julien, Konstantin | Laser | Phase-offset | We recognized that the output power of the
pump laser was instable when externally triggered
with 200kHz (stand-bye frequency of ESR). |

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 |
