Danyal | General | setting up ESR | The operators are still busy extracting the
beam from the SIS18 towards the ESR and injecting
it into the ESR. |

Danyal | General | bad ESR vacuum | I just heard that the ESR vacuum is quite
bad.
There was a small vacuum problem a while |

Danyal | General | instabilities in ion frequency | The ion beam moves around, pretty arbitrary.
See picture.
ESR crew believes that it is not due to fluctuations |

Danyal | Accelerator | short break between 13:30 and 15:30 | There will be a short break (2 hours) this
afternoon. Between 13:30 and 15:30.

Danyal | DAQ | more stability by bunching | Because the C3+ part of the ion beam is properly
bunched, it is no longer so sensitive to
the drifts caused by the e-cooler.

Benedikt | General | Status update | Right now, we have to adjust the ion beam
a bit to overlap better with the laser beam.
We keep the laser wavelength at resonance |
