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

|
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"

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.

|
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
