|
I just performed a backup of all data (+log-Files) that were collected until now to the two RAID HDDs.
For DAQ1: /media/sdc2 - last file 229Thor7889.lmd. Please note, that the naming sceme on DAQ1 is inconsistent - please look for the filenumnbering

Thu Apr 14 08:41:42 2022, Carsten, Accelerator, Low intensity at the experiment after series of failures during the night
|
After the recovery from the failures during the night, we see much lower intensity at the experiment (measured with the particle detector count rate).
Instead of 8000-10000 cts we see only 3000-4000cts at comparable SIS intensities.
Also ESR cooler seems to be slightly unstable (wiggling lines) during injection. However, it is visually evident from the Schottky that the injected intensity |

|
We had no beam since about 1000. Also, we are still trying to find out why we have such a low intensity in the expereimnt.
Presently, there is a planned maintenance in the UNILAC, beam is expected back in 25-30 mins.
The profile grid TE3 in the transfer beamline in front of the target will be used to check if the extracted SIS beam has changed compared to before the |

Sometimes we see a broad sideband at lesser schottky frequencies to the high intensity thorium beam.
Pic 1 shows the relative broad sideband on the left.

We scan the wavelength scan range is 322.01 - 321.60 nm
before the first scan of the new wavelength range we changed the high voltage divider ratio in Labview from 248514 to 248517, which is the correct value |

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)!!
