Patrick, Rodolfo | Laser | Wavemeter | We coupled the laser through a multi-mode
fiber into the wavemeter.
With the main amplifier enabled, we got enough |

Patrick, MBS Max | DAQ | MBS procedure | It is possible to keep go4 running now. Summary
of the procedure:

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, 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 | 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 | DAQ | Keep go4 running (in theory), MBS | To accumulate more data into the opened go4,
do not restart MBS, but just

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.

Wed May 11 22:19:17 2022 |
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 | Analysis | start go4 before laser scan | It is necessary to start go4 before you start
the laser scan. Otherwise you get an offset
in the laser Step plots. |

Max, Rodolfo | Laser | MRC Settings for 209Bi | We have change the laser settings for the
spectroscopy of 209Bi.

Max, Patrick, ~Konstantin, Ragan, Ken | Runs | runs night shift 30.05. | These are the first runs of the substitute
beamtime.

Max, Patrick | Laser | Beam overlap | The ion beam positions are (+- 1mm):

Max, Kristian, Sebastian | DAQ | laser scan, laser step and laser busy checked | We checked all three signals in the Messhütte.
Laser scan and laser step are OK.
The Laser busy signal is for large increments |

Mon May 16 17:38:38 2022 |
Max, Danyal, Wilfried, Rodolfo | General | laser bunch timing | We overlapped the laser and ion bunch in the
time domain.
Therefore we delayed the bunching HF in order |

Tue May 31 17:22:09 2022 |
Max, Carsten, Danyal, Rodolfo, Wilfried | General | change E-cooler current I_e = 50 mA |
At 17:15 we changed again the E-cooler current
I_e = 50 mA

|
Tue May 31 15:19:58 2022 |
Max, Carsten, Danyal | General | scans for different E-cool currents |
until 15:15 we have measured with I_e = 100
mA (3 loops per file)

Thu May 12 15:50:33 2022 |
Max | Accelerator | No ESR beam | Since 13:30 we have no beam in the ESR. There
is a problem with the ESR septum.
The magnets department is investigating. |
