Tue Apr 5 09:45:47 2022, Danyal & Yuri, Accelerator, beam is back in the ESR - a slit was moved in
|
And now also in English :)
The ion beam is back in the ESR!

Tue Apr 5 09:39:01 2022, Danyal & Yuri, Accelerator, Strahl ist wieder im ESR - Schlitz war reingefahren
|
Der Strahl ist wieder im ESR!
Angeblich war einen Schlitz, oder sogar 2, reingefahren worden.
Es könnte entweder der GEEXDR11S und/oder den GEEXDR1AS gewesen sein.

|
Since we cannot write on lustre, as a temproal solution two RAID 1 (mirror) USB hard disks with cpacity 6 TB each are installed.
The disk on the lxg1297 the disk can be accessd at /meida/sdd2
an on the lxg0155 at /media/sdc2

Mon Apr 4 15:32:38 2022, Kristiand & Sebastian, DAQ, Go4 Backup Code
|
Due to some code changes (PMT over wavelength historgram) Kristian and I backuped a working Go4 code in the current go4 folder on the atplaser linux account.
It can be found in the subfolder "working go4 code 4.4.2020"

Mon Apr 4 15:27:31 2022, Sebastian, DAQ, PMT over wavelength histogram
|
Kristian and I tried to create a "PMT over wavelength" histogram under step2Anl/LabView.
Unfortunately, the code ist still in progress and does not work yet.

Sun Apr 3 18:52:30 2022, Konstantin, Calibration, Laser ion beam overlap
|
We measured vertical and horizontal ion beam positions. Unfortunately, the horizontal scraper positions can not be manipulated
by the "Device Control" software. Robert Boywitt has supported us a lot to get the drives moving by using the expert software on
a local control PC, which can only be remotely accessed from beapc032 with the usual experiment account "atplaser". In the first

We (Konstantin and I) have optimized the TEM "laser-beam position stabilization".
- I took some pictures (screenshots) about the current setting*.

I co controlled all detector signals and
adjusted the threshold to be just above
the noise. I will double check this when

As of Yuris post in the elog the positions (Info from H. Weick):
The postion of the particle counter behind the cooler is 21.6 m behind the middle of the cooler.

Sun Apr 3 11:40:48 2022, Shahab, Yuri, Detectors, 245 MHz Resonator tuned to new frequency
|
resonance frequency changed from 243.2 MHz to 244.692 MHz by reducing the value of both of the plungers from 395 to 325. Now after movement, the peak is
on the resonance. |

We the mid- and night shift (Wilfried, Simon, Patrick, Ken and me) we not able to manipulate the scrapers in the E-Cooler.
- Carsten contacted Markus concerning this issue.
