Attached you find a manual for the software used to control the movement of the XUV detector and the copper mirror detector.
The software is also used to set the electrode voltages and coil currents of the XUV detector. |

|
The connection to the XUV and Cu were lost during the nightshift.
The XUV detector was in the park position,

Mon Apr 11 11:05:35 2022, Sebastian, Kristian, Laser, Check laser power
|
we checked the UV laser power at 10:15 am. It was only 8.5 - 9 mJ. Pumping power was 460 mJ, which is the maximum output of the current system. We should
change the flashlamps soon |

Wed Mar 16 08:31:52 2022, Kristian, DAQ, Check cables and timing
|
Konstantin and I generated a signal in the Messhütte and sent it to the ESR.
There, we used a 44m BNC cable that was sufficently long to reach all detectors.
Our signal was connected instead of the PMT/PD. Hence, it was a roundtrip measurement.

|
| It is planned to change the scan range of the laser wavelength from 322.41 - 322.0 nm to 322.01 - 321.6 nm @ 4 a.m. |

We agreed to indicate changes in the go4 analysis code according to the
following scheme

Sat Apr 9 14:15:44 2022, Kristian, Max, Konstantin, DAQ, Change in LV code
|
We changed the LV code so that the Cobra Set Wavelength is permanently sent. Before it was only sent once at the beginning of each laser step. This, however,
lead to too much data for the LV->MBS server.
This was fixed by inserting a 250 ms wait in LV (in Krypton data VI). Basically, all LV values are now updated every 250 ms, which works fine with MBS |

Fri Apr 8 11:02:04 2022, DW, YL, RSS, SL, , Change h=2 to h=1

After changing to h=1
The frequency manipulation #5: f=242.021487MHz (124th harmonic) [no bunching]
Manipulation #7: f=242.021812 MHz [with bunching] |

Fri Apr 8 01:48:57 2022, Patrick, DAQ, Bugged Trending plots?
|
The wavelengths/frequencies shown in the graph in the labview window do not match the wavelengths/frequencies in go4.
Compare the picture which shows an incomplete laser scan although the scans in the labview window are completed (The measurement was started at an 'elapsed
MBS time' of 2700s and took 1700s/28min).

|
Sat Apr 9 04:40:01 2022, Patrick, DAQ, Bugged Trending plots?
|
The problem from yesterday (ID:147) still persists. All the plots (not only the labview stuff) comes in too late in go4. However, the time axis is correct,
see picture. |

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

|
I just performed a backup of all data (+log-Files) that were collected until now to the two RAID HDDs.
For DAQ1: /media/sdc2 - last file 229Thor7889.lmd. Please note, that the naming sceme on DAQ1 is inconsistent - please look for the filenumnbering

|
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 11 18:46:31 2022, Rodolfo, Sarper and Konstantin, Laser, Alignment-check
|
We cross-checked the laser-ion alignment. The horizontal position was optimized. However,
since the laser beam is much larger than the ion beam, this was not an issue for measurements, which
have been performed during the last shifts.
