 Fri Apr 8 14:12:57 2022, morning shift, DAQ, timing for h=1 
|
The timing for h=1 has been set up
The time window is now twice as large as before!

Sat Apr 2 01:27:25 2022, Jan Glorius, Runs, test runs 02.04.2022
|
Beam settings:
primary beam
copper stripper

Wed Apr 6 18:51:33 2022, Danyal & Carsten, Accelerator, target bump
|
This afternoon, we found out that Sergey has also implemented a "target bump".
Although we do not use a target, this bump is still convenient because
we can move the ion beam such that is passes perfectly through the Cu mirror.

Wed Apr 6 08:06:02 2022, Danyal, DAQ, stopped NTCAP data acquisition
|
I stopped the NTCAP data acquisition at 8 AM.
Let's hope that the file contains good data. |
|
Sun Apr 10 06:39:16 2022, Kristian, Marek, Max, Runs, runs morning shift 10.04.
|
These are the measurement runs of the morning shift (10.04.).
|
|
Thu Apr 7 14:04:36 2022, Paul Indelicato, General, no beam until 17:00
|
10:10 There is a problem with the UNILAC.
The repair will take several hours. (4 hrs?)

Tue Apr 12 12:41:20 2022, Alexandre, Sebastian, Accelerator, no beam in SIS18

Mon Apr 11 10:31:07 2022, Kristian, Sebastian, Alexandre, Danyal, Paul, General, new laser wavelength scan range 322.41 - 322.00 nm
|
new wavelength scan range is 322.41 - 322.00 nm
at 10:31
|
|
Tue Apr 12 21:56:54 2022, Volker, David, Pierre-Michel & Danyal, Alexandre, Sebastian, General, new laser wavelength scan range 321.62 - 321.10 nm
|
New wavelength scan range is [B]321.62 - 321.10 nm[/B]. Before the new scan range (compare old scan range in [URL=https://elog.gsi.de/esr/E142/215] Entry
215[/URL]) was applied,
the cooler settings were slightly modified. Current was changed from [B]50 mA to 40 mA[/B], correction voltage was changed from [B]3943 V to 3948 V[/B]. |
|
Thu Apr 7 14:13:27 2022, Danyal, Detectors, new PMT south
|
I have replaced the PMT south (looks at the gas target).
in the hope that this will produce less dark counts.
Thus far, the dark countrate is low (few Hz).

DAQ1: lxg1927:/data.local2/BeamTimeTh22/

Fri Aug 6 10:40:54 2021, Rodolfo, DAQ, mbs in atplaser
|
The "MBS program" (data acquisition) is now located within atplaser@r4l-41, in the folder "th21":
|
|
Thu Apr 14 06:29:18 2022, Max, Sebastian, Accelerator, lesser ESR injection intensity
|
We now have less ESR injection intensity (see screenshot attached).
This can also be seen in the count rate after "UNILAC/SIS failures".
|
|
Fri Apr 15 12:42:18 2022, Max, Danyal, Carsten, Konstantin, Patrick, Simon, General, laser wavelength range changed: 320.12 - 319.60 nm
|
Runs of the morning/afternoon/night shift. The wavelength range is now 320.12 - 319.60 nm.
|
|
Fri Apr 8 14:43:50 2022, Wilfried, DAQ, laser timing - Q-switch start
|
| below are my notes concerning laser timing / Q-switch start |
|
Fri Apr 8 14:46:02 2022, Danyal & Sebastian & Volker & Ken, Detectors, high dark countrate Cu PMT solved
|
The problem - "discovered" by Volker and Ken - of the high dark countrate of the Cu PMT has been solved.
(when the Cu mirror was moved in, the dark countrate was very high ... also without ion beam)
|
|
Sun Apr 10 04:07:53 2022, Patrick, DAQ, go4 shows wrong frequencies and wavelengths
|
[B]Update (ID:194):[/B] In labview "Stop All", close labview, stop python script (ID:197), close wavemeter. Then restart wavemeter, python script, labview
an mbs.
|
|
Sat Apr 9 13:45:42 2022, Max, Kristian, Runs, first scans with LV problem solved!
|
This is the first time with LV buffer problem solved (see Elog ID: 184). Before the PMT signals were out of sync with the wavelength data!
We concluded to scan with step sizes of 0.002nm, scan range of 0.5nm (f
nm), dwelltime = 150(5s), loops = 2 (approx.: 30min measurements).
|
|
Fri Apr 8 15:39:36 2022, all, Runs, first data after timing set up
|
started taking data again
started at 15:40
|
|
Thu Apr 7 11:11:31 2022, Max, Sebastian, Laser, dye changed, pulse energy measurements
|
We changed the dye at 10am.
We increased the pump power for the dye Laser to 480mJ (before 450mJ). New calibration factor is 29 for Quanta Ray monitor signal.
