Yuri, Beatriz | General | Optimisation beam position on target and scraper position | 2021 |
Optimised overlap with the target by shifting the beam from -11.5 to 12.8 mm. This lead to an increase of the DSSSD rate of a factor between 2.5 or 3.
Adjusted scraper position by looking at x-ray rate and move it from +1 to +2. |

Jan | Accelerator | FRS degrader failure | 2021 |
Maybe, our degrader in FRS was removed by hand at (~13:40 26/05/21)
It is put back now (~13:10 27/05/21)
All runs taken in this period have to be double checked!
However, the xray lines from this night show Te for k_alpha and K-KREC
It is also possible that the readout of this degrader motor was just wrong due to its state as hand-controlled. |

Helmut Weick | Accelerator | FRS wrong status display for one day | 2021 |
By checking the log files we realized that from yesterday 26.05. 13:44 - today 13:05 the FRS degrader was shown as out.
TS3ET7US should be at -420.0mm not at -580mm (=out). This 3.26mm Sci is used as a degrader and is essential.
After recognizing we set the drive controller back to remote and moved the degrader to -420mm (at 13:02)
The wrong values start on 26.05. at 13:44 and show variation until 16:11 until over night it was always shown as out.
It was tested today (~14h) that if you really move it out no beam is injected into ESR, but beam and even Te was observed in ESR last night.
The drive controller was in manual mode and it may not have given correct updates.
But it was also tested today that drives on the same crate get updates even in manual mode (at ~16h with TS1DG5_S and TS3ED7DS).
We also checked graylog. No drive command was issued yesterday in this time period, whereas the drive commands for testing today can be clearly seen.
Yesterday other drives in S4 area on the same controller were tested. This is most likely the reason for the manual mode. |
