 Thu Apr 7 10:10:31 2022, Ragan, Yuri, Danyal, Accelerator, Problem in UNILAC
|
| The power supply of the UNILAC magnet is broken. The repair will take up to 6-7 hours. |

Thu Apr 7 09:58:55 2022, Ragan, Yuri, Danyal, Accelerator, Kicker problem solved
|
| The kicker problem is solved and the beam is back in the ESR. |
|
Thu Apr 7 09:23:18 2022, Sebastian, DAQ, DAQ1 & DAQ2 - 1kHz and delayed cs removed
|
Questionable 1kHz and delayed common stop signals has been removed.
These two cablings were for some previous tests. |
|
Thu Apr 7 08:43:19 2022, Danyal, Yuri, Ragan, Accelerator, again no injection in ESR - ESR kicker problem
|
we had no injections in the ESR again
it turned out that the injection kicker of the ESR has a problem |

Thu Apr 7 07:40:09 2022, Danyal, Max, Sebastian, DAQ, No beam and DAQs crashed
|
since shortly after 7 AM we have no beam in the ESR
(reason unclear)

Thu Apr 7 05:55:17 2022, Ken Ueberholz, Detectors, XUV-Detector Mesytec crash
|
When the XUV-detector has to shut down unexpectedly, it can happen that the Mesytek power supply crashes and can't be
communicated with. If this happens the Mesytec PS needs to be restarted from hand inside of the ESR. This can be done by
restarting the crate located at the bottom of the XUV-detector.

|
(MBS server should be running at the LXG0155 machine. If not you will get an error message. Then start the server - last command in console)
Just enter the following commands in the console of any PC

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)!!

|
A lot of cables were wrongly or not
connected to the DAQ 2.

Thu Apr 7 03:06:15 2022, Patrick, DAQ, DAQ file sizes
|
The file sizes of DAQ1 (229Thor) and DAQ2 (229Th, "Carstens DAQ") are different.
During 20min of laser scanning DAQ1 saves 4 files while DAQ2 saves 2 files which was 3.3 GB and 2 GB, respecively.
[B]The file sizes of DAQ2 should always be greater than those of DAQ1, because of extra ADC data![/B]
