Dima, Zac, Sid, Kanika, Ragan, Shahab, Beatriz | DAQ | new file name and settings for 245 MHz |
new settings:
1.8 seconds recording on 245 MHz on RSA02
starting from file name:
2025.04.04.18.36.32.895

DAQ stopped with last file in RSA1-2025.04.04.17.58.49.340.tiq
Now the plan is to change one of the analyzers to narrow band recording for longer from the 245 Schotkky. |

H. Weick, S. Litvinov | Accelerator | ESR scraper setting |
the new scraper setting for good isochronicity but still acceptable intensity losses is:
Done at ~ 15:00 today.
GEEXDS1HA (outside) = -8 mm
GEEXDS1HG (ToF-det-aperture) = 20.5 mm
GE01DS3HG = -84.2 mm (fully open is -130 mm)
in addition, a detector pocket is in GE01DD2IG = 1.7 mm |

H. Weick, S. Litvinov | Accelerator | slits after target, Bio_REM alarm |
A Bio-REM detector on the roof of ESR caused an alarm and shut down the whole accelerator.
Too much primary beam going to ESR, noe we avoid it by catching the primary beam at TE4 slits.
The distribution on current grids looks liek in the LISE simulation, we cut at 5mm.
The beam come sin three charge states tehouter ones 82+, 81+ anyway do not make it to ESR, we need to cut also the 80+ at least half.
Then the dose rate on ESR roof is much lower 0.8 uSv/h -> 0.2 uSv/h. |

JG, ID | General | pleiades detectors moving |
We started moving the pleiades detectors at 16:13 04-04-2025.
We have the inside pocket (GE01DD2IG) at 2mm.
The outside pocket (GE01DD2AG) cannot be moved by the Device Control program, some problem with the tolerance (error message: outside of tolerance). Need to go in in a short break and check what is wrong.
We will partly scrape the beam. |
