 Sat May 8 15:18:23 2021, Michael, Wolfram, Yuri, General, Beam Settings changing
|
| Beam settings are being changed back to 78Kr beam at 467 Mev/u. |

Sat May 8 11:42:21 2021, Yuri, Accelerator, KPs
|
EO1KP03 was on = -44.9 A
E01KP05 was off, now is on = 3.67 A
The beam is on the right frequency, but the width is still very broad. |
Sat May 8 10:51:41 2021, Akash, Nic, Jelena, Zsolt, Calibration, ESR settings seem different 
|
| Settings don't look the same...so we are not yet writing files unless sure. |
|
Sat May 8 08:44:32 2021, Akash, Nic, Jelena, Zsolt, Accelerator, No Beam!
|
08.43am: Beam stopped. HKR looking into it. Reason: they mentioned they don't know yet!
10.10am: SIS resumed operations. However, there are some issues with magnet power supplies for ESR and hence we still don't have beam. HKR member went |

Sat May 8 08:12:02 2021, Akash, Nic, Jelena, Zsolt, General, SIS, ESR time structure changes
|
The structure of SIS extraction seems to have changed a little...also for ESR injection.
In the span of a few minutes both the structures changed again...to look more like in the previous shifts, with lesser or no negative component. |

Sat May 8 07:34:08 2021, Akash, Nic, Jelena, Zsolt, General, Zoom has its own mind
|
| Zoom kicked us all out... we managed to get back in...screen sharing is back on. |

|
Things look ok. No settings have been changed...
Analysis attempts are going on... |

Sat May 8 03:08:57 2021, Rui-Jiu Chen, DAQ, Change reference level to -50dBm
|
Start a new run. The data of new run is in :

Sat May 8 03:05:42 2021, Rui-Jiu Chen, DAQ, Change reference level to -60dBm
|
Start a new run. The data of new run is in :

Sat May 8 01:43:23 2021, Helmut Weick, Accelerator, 70Se setting
|
If gamma_t = 1.3955 Tm stays, we will need Brho = 6.21902 Tm for 70Se.
The corresponding ESR Brho setting will be a bit shifted.
It then requires E-SIS = 446.55 MeV/u to get 70Se to this Brho and gamma_t.

EXCEL table with all possible fragments injected into ESR.
The path length in ESR, gamma_t and harmonic are adjusted to the 72Ge data.
Some lifetimes are limited but all intense lines are >30s in lab system.

|
| The signal of the transformer on the lower right panel is not really beam related. It is mostly noise. Changes are not so expected with this low beam intensity |

Fri May 7 23:08:44 2021, Michael, Kanika, Accelerator, Beam issues for short duration
|
| The beam was lost for a few minutes from 23:01 to 23:06. It is back now. |
|
Fri May 7 22:48:33 2021, Chris, General, still running...
|
| In anticipation of the imminent shift change, a snapshot of how things look. |

Fri May 7 22:00:36 2021, Chris, Accelerator, brief beam loss
|
| Brief interruption in beam, ~21:42-21:51. |
|
Fri May 7 20:34:27 2021, Kanika, Michael, Shahab, Runs, back to 15 sec recording
|
| now we are going back to 15 sec operation. Cave M (bio) operation is over |
