Sat Jun 15 03:46:34 2024, Night shift, Accelerator, GSI down
|
All quadrupole and dipole magnets at SIS and ESR are out of order. Repairs can be expected earliest tomorrow evening. No shifts will take place before 6pm.
Have a look at your mails for details. |

Fri Jun 14 13:14:29 2024, Konstantin, Bernhard, Peter, Lukas, General, DAQ crashes at :10
|
10 Minutes past a full hour (XX:10) the windows PCs (sometimes) loose connection.
This causes the labview server & the laser remote ctrl to crash.

Very successful shift, no crashes until 11:10
Previous night shift had problems with the pulse laser starting around 3am.
Something was loose at the FCU. Rodolfo was called in and was able to fix it.

Thu Jun 13 22:08:07 2024, Dayshift, Accelerator, Problems with Accelerator?
|
It seems to be that there are some problems with the injections in the ESR.
The last 2 accumulation cycles showed that wheter only a small amount of ions are injected into the ESR or the injection is missing.

Thu Jun 13 18:38:24 2024, Rodolfo Sanchez, Julian Palmes, Sebastian Klammes, Laser, Laser Dye change - new MRC settings - scraper checks of laser beam
|
We changed the dye at ~3pm.
After some fine adjustements of the laser we had to change the MRC settings, because the laser position changed.

Thu Jun 13 18:23:46 2024, Julian, Laser, Restarting the laser controller
|
If the laser controller is locked up again, the little display will show an error message after an attempted medusa scan.
To restart it, follow these steps:
1.) Unlock the beam stabilization.

|
To realize the shortest bunches possible, we check the bunch length as a function of two different bunching amplitudes. With the bucket fill set to 1.0
we observe the spectra compiled in attachment 1. The second attachment is recorded with a bucket fill 0f 0.2.

Thu Jun 13 10:42:02 2024, Danyal, General, Question
|
What is the ion beam lifetime, according to the DCCT and Schottky?
Can somebody measure it, please?
Yesterday we could not see a fast drop in the "main" beam.

Thu Jun 13 10:32:29 2024, Konstantin, Accelerator, (Proper) Cooler settings
|
We change the acceleration voltage of the electron cooler and observe the platform high voltage and the count rate at the particle detector south.
Cooler current at 100mA.
