Sat Apr 2 22:43:36 2022, Carsten, , Ring set-up for 229/89+, scraped and bunched, Iel=500mA at injection and 100mA during measurment
|
The ring SIS/ESR were set up for 229/89+. Pölease note that this not only 1e- Th but ponteially also the isobars of Ac (0e-1)/Pa(2e-, strongest) and U(3e-).
SIS eenrgy plus 3.5 MeV/u w.r.t. to the 238U92+ settings. We nearly don't see any of the primary beam in the ring
Cooling energy is 208998 KeV (read from the ESR multimeter).

Sat Apr 2 23:16:55 2022, Carsten, , Cu mirror and CsI moved in and out of the ring
|
| Ken tested the Cu-mirror and CsI disk Detector. They move without a problem and don't scrape the ion beam. |
Sun Apr 3 00:41:45 2022, Ken Ueberholz , , Xuv-Detektor Signale 
|
The Xuv-detector cabel channels seem to be
wrongly labeled in the Messhütte (see
picture) and are propably also wrongly

I co controlled all detector signals and
adjusted the threshold to be just above
the noise. I will double check this when

Thu Apr 7 04:48:58 2022, , , ToDo's for 07.04.
|
Some ToDo's for the next shift:
- Work on Laser stabilisation 2nd stage in the ESR
- Mesytec power supply of the xuv-detector crashed and needs to be restarted in the ESR. Simply turning it the crate off and on again)!!

After changing to h=1
The frequency manipulation #5: f=242.021487MHz (124th harmonic) [no bunching]
Manipulation #7: f=242.021812 MHz [with bunching] |

Switched the CAEN TDC back on and changed the threshoolds for the ADC to:
