Finn, Simon, Konstantin, Rodolfo | DAQ | Bunching - ammendment late shift | Some 209Bi80+ beam was provided for tests
measurement over the weekend. Currently the
beam is bunched at the second harmonic, corresponding |

Finn, Simon | General | Beam not bunched (?) | We think the beam in the ESR is not bunched.
There is a clear difference in PMT signal
if ions are in the ESR compared to no ions |

Finn, Simon | Detectors | PMT north | In contrast to PMT Mid, the difference between
ions and no ions in the ESR (see screenshot
scaler) is not visible. Signal gets higher |

Finn, Simon, Carsten | General | Night shift sum up - ammendment day shift | As the beam in the ESR is most probably not
bunched, there was not much we could do.
During the night shift we:

Carsten | Detectors | Scrapers do not work reliably / Scraper positions for further tests | I tried scraping with pressurized-air devices
in order to verify the beam poistion. All
4 devices that we use do not work reliable |
