Max, Wilfried, Volker | Laser | laser bunch timing | We overlapped the laser and ion bunch in the
time domain. The delay has to be set on the
module above the laser and NOT in the ESR |

Max, Wilfried, Zoran | Accelerator | NO BEAM UNTIL TOMORROW MORNING | The problem at the ESR septum is serious.
They have to remove the broken part and try
to repair it.

Patrick | DAQ | Laser scan complete signal off | As in ID:46, the 'laser scan complete' again
is not coming in.
It is not very useful to repeatedly fix cable |

Patrick, Kristian | DAQ | Changed PMT North CFD channel | In run 8134 - 8135 PMT North showed a super
high background rate. After the scan we checked
the signal cables.

Patrick, Kristian, David, Ruijiu | Detectors | Switched off nitrogen | Background counts with nitrogen and air.
Less multiphoton events with air (see pictures,
histogram extended to 30 with nitrogen).

Patrick, Sebastian, Volker, Guy | Laser | Laser - bunch timing | We added the delay and gate generator in between
the bunch trigger and the CFD to move the
timing of the PMT middle signal relative |

at the PMT thresholds and the widths. In
order to do so we looked at the Raw Signal |
