|
Attached are the proposals submitted to and approved by G-PAC. |
|
Tue Apr 1 17:08:13 2025, JG, ID, MC, CG, Detectors, pleiades in position
|
The pleiades detectors are now moved into a position which does not disturb the stored beam.
inner detector: BGO
device: GE01DD2IG
position: +20mm
scraping beam: not possible
outer detector: GAGG
device: GE01DD2AG
position: -55mm
scraping beam at: -45mm
These positions are fixed, i.e. not moving automatically. |
|
Fri Apr 4 16:12:54 2025, 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. |
|
Tue Apr 1 14:23:01 2025, JG, General, Pleiades pocket position tests
|
We started playing with the detector pockets of the pleiades arrays at 14:23 01.04.2025.
This might disturb the beam sometimes.
The beam is lost in SIS at 14:35.
Beam came back at 16:40, we continued playing with pleiades positions until 17:14. |
|
Wed Apr 2 23:40:23 2025, JEL, ZN, General, Screenshots taken just as beam came back
|
We are seeing spills being received but no peaks are seen in the analyzers.
We are seeing several intermittent losses of beam. Awaiting action to see if it stabilizes.
23.51 Beam is back and we see the nice spectrum in the analyzer. |

Thu Apr 3 02:59:15 2025, JEL, ZN, Runs, Screenshot, beam received, baem lost, beam back again
|
Beam is back for 10 mins-
The peaks on the analyzer appear shifted to the right.
As I write this the beam disappeared again.... 02.59
and back again at 03.08 |
|
Thu Apr 3 03:48:40 2025, JEL, ZN, Runs, Screenshots
|
The peaks in the analyzer are slowly shifting back to the original position.
Note that a quadrupole was the cause of the issue 45 mins ago and it was cycled. Might be relevant... |

Fri Apr 4 16:01:09 2025, ID, MC, Kanika, General, 186Hf running now + Lassie screenshots
|
Tuning is finished, 186Hf is running. Sharp peaks now. |
|
Wed Apr 2 15:46:24 2025, ID, HA,MW, General, Beam back in ESR,
|
beam is back, we started DAQ again. All files created after 15:45 should be good from now on. |

We managed to take some screenshots while Shahab harrassed us with AI-created "RammstAIn" music... happy to end my shift now! |

Looks a bit more regular now (FRS people having dinner???) |
