 Thu Feb 27 16:30:57 2025, Konstantin und Rodolfo, DAQ, HF Signal
|
| We have exchanged the HF-Signal in the DAQ Electronic: from Dummy-HF to the real HF from accelerator. |
|
Thu Feb 27 21:23:02 2025, Jens, DAQ, Python Data Channels
|
Python variables and names in DAQ
Because the Name of variables in DAQ doesnt match the the real variables, here is List of the channels and what value is in this channel
|
Fri Feb 28 00:44:31 2025, Denise, Sebastian, DAQ, Shutter auf - Shutter zu Go4 Signale 
|
Shutter auf (TDC Kanal 12 / Go4 Kanal TrS11_Shutter auf)
Shutter zu (TDC Kanal 13 / Go4 Kanal TrS12_Shutter zu)

Fri Feb 28 17:36:15 2025, Konstantin, DAQ, Trigger events from accelarator
|
| We will use GENESIS to create trigger events (injection, ...) for the DAQ |
|
Fri Feb 28 20:44:04 2025, Konstantin, DAQ, Updated Channel list

Sat Mar 1 03:45:07 2025, Denise, Benedikt, Sebastian, DAQ, PH100 Gentecs @ Medusa
|
Die zwei PH100 Messkoepfe am Nordwest und Suedwest Tower werden delayed in Medusa angezeigt und die Daten werden nicht an Medusa geschickt.
Letzteres haengt wohl mit den benoetigten 10 digits zusammen die MBS erwartet.
|
|
Sat Mar 1 03:58:17 2025, Denise, Benedikt, Sebastian, DAQ, DAQ Daten xchecks
|
Die allgemeinen DAQ Daten wurden ausfuehrlich crossgechecked und kommen nun alle an wie sie auch in die DAQ reinlaufen sollen.
Allerdings mussten die zwei PH100 Gentec Messkoepfe aus der DAQ gestrichen werden, da die Daten extrem verzoegert in die Slow Control Aufnahme reinlaufen. |
|
Sat Mar 1 04:02:59 2025, Denise, Benedikt, Sebastian, DAQ, Lokale Datenaufnahme auf LXG1049
|
Die Daten werden LOKAL auf dem LXG1049 unter folgendem Verzeichnis gespeichert:
[B]/data.local2/2025_krypton/[/B]
|
|
Sat Mar 1 04:10:48 2025, Denise, Benedikt, Sebastian, DAQ, DAQ Terminals
|
Es gibt nun 3 Terminals am LXG1049 die immer offen sein sollten!
|
|
Sat Mar 1 07:01:41 2025, Denise, Benedikt, Sebastian, DAQ, UV Wellenlaenge in Python implementiert
|
Die UV Wellenlaenge des WS7 wurde zusaetzlich zur WS7 Frequenz in Medusa hinzugefuegt um den korrekten Wellenlaengenscan des Pulssystems besser online zu
verfolgen.

|
Sat Mar 1 13:45:42 2025, Konstantin , DAQ, Gentec readout
|
Gentec readout is now included in the general slow data acquisition. The issue was that the buffer of the power meter was not emptied fast enough. Now,
the data is read out permanently in a separate thread. |
|
Sat Mar 1 16:33:22 2025, Konstantin, DAQ, Restart of Go4
|
Restart of go4 before new scan:
1. Stop Acquisition (Stop button right next to the green play buttons)
|
|
Sat Mar 1 17:43:18 2025, Reinhold, Jens, Natalya, Danyal, Denise, Benedikt, DAQ, Scanbereich 257.175 nm - 257.675 nm

Sat Mar 1 19:19:25 2025, Konstantin, DAQ, Offline Analysis
|
A copy of the current go4 analysis is placed at atplaser@lxgs1055:/kr_analysis. Use the usual Go4 startup routine to start an offline analysis of data.
They should be copied into the folder lxgs1055:/data.local2/E0075. To combine different
lmd-files, simply create a file like "FirstScan.lml" containing the paths of the individual files. After this you can read the lml file with go4. |

Sun Mar 2 03:07:43 2025, Denise, Benedikt, Danyal, DAQ, 0.0012 nm shifted scan: 257.1738 nm - 257.6754 nm

Sun Mar 2 18:55:30 2025, Jens, Reinhold, Danyal, DAQ, Main Scan range (4 blocks) shifted by -0.0012 nm --> one more scan
|
We decided to scan the main range, shifted by -0.0012nm, one more time in order to have the non-shifted AND the shifted range both 3x !
[TABLE border="1"]
|
|
Sun Mar 2 23:05:16 2025, *Jens, Reinhold, Danyal, DAQ, extended normal scan range (no shift): 257.6750 - 257.8022 nm
|
We will extend the max normal scan range by 3 measurements

|
Mon Mar 3 16:19:18 2025, Konstantin, DAQ, changed shutter timing - effective from 03.03.2025 @ 16:24 !
|
The power and the fluctuations of the laser should be recorded in the XUV Data, so that the rate can be corrected.
Therefore the shutter timing was changed.

Mon Mar 3 20:14:10 2025, Jens, Konstantin, Reinhold, Danyal, DAQ, -0.0012 nm shifted whole range scan (@2nd ion energy)

Thu Feb 27 09:59:08 2025, Konstantin, Calibration, HV-Divider
|
The readout of the HV divider runs on a RaspberryPi inside the HV-cave of the electron cooler.
Starting from 2025-02-27 09:42, the divider ratio was changed from 248517 to 248515. Usually, the
readout should run continuously. If not, the following procedure must be applied:
