Sergey Litvinov will now try to setup the e-cooler to cool the beam in the ESR.
The data taking has been stopped (except the NTCAP). |

Wed Jun 30 14:48:54 2021, Oliver, General, Data taking - and not...
|
We just started data taking. But a few minutes later the main experiment needed to do some adjustements to the beam. This interrupts us for a couple of minutes... |

Wed Jun 30 14:52:28 2021, Oliver, General, Re-Started data taking...

Main user is finished. We started data taking again... |

after optimizing the scrapers we have reached the highest possible resolution in the isochronous mode.
starting data taking with this new settings.

So far, we keep the setting as it is and wait for experts to come in.
Few spills are missing from time to time. One of the peaks stays usually in the spectrum when this happens.
Analysis of the last hours is being performed by the remote shift, in case it is useful. Some plots in telegram. |

At the moment we see a second peak to the left of each intense line.
The distance between the main peak and the shadow is roughly the same for each peak.
This hints to a sharp fall in the isochronicity curve.
Helmut now tries to remove these shadows by using different scrappers. |

Scraper settings have been played around with to try and remove satellite lines...
Helmut has now set scraper id GE01DS_H at -45mm (in position)

Sun May 9 13:15:38 2021, Liliana Andrew, Runs, Stopped data taking during modifications for the beam energy
|
Beam energy to be increase to move Mn into the ring.
First step we set the energy to 445 MeV.
The effect of the change can be seen on the plot: Right is how it was before and left after the change. |
