Mon Apr 11 07:54:37 2022, Danyal, Alexandre, Kristian, Sebastian, Accelerator, Jump in E-cooler voltage
|
We saw a jump in the E-cooler voltage at about 7:50.
jump from 209619 to 209610 V

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.
|
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!
|
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)
|
Thu Apr 7 15:18:25 2022, Danyal & Sebastian, DAQ, DAQ channels
|
We checked again the cables for both DAQs
(on Carsten's kind request)
|
Wed Apr 6 08:31:54 2022, Danyal & Regina, General, ESR had some errors
|
Regina noticed that the ESR was "red"
This means that there are some errors.
|
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. |
Wed Apr 6 09:30:53 2022, Danyal, Accelerator, ESR is blue again - errors are fixed
|
The ESR is "blue" again.
The errors (scu related) have been fixed.
|
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).
|
Mon Apr 11 10:17:01 2022, Danyal, Accelerator, Interlock - reset
|
10:17
Wie heutemorgen in der Sitzung (morning briefing) vereinbart,
führt Herr Florenkowski einen Interlock und danach einen Reset von E02MK durch.
|
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] |
Sun Apr 10 15:29:37 2022, Carsten,Sarper, Accelerator, Ecooler failed
|
Ecooler failed @15:23 Carsten is fixing it
Fixed @16:00 |
Sat Apr 9 15:47:21 2022, Carsten, Rodolfo, Sarper, Patrick, Runs, Afternoon and night shift runs
|
After the morning shift, we got new increment (nm) for the laser scanning. We are now scanning 2 nm of wavelength range in 5 big steps (5 x 0.4 nm). Started
with 323.2 nm - 322.8 nm range. Every big step (0.4 nm) is scanned with 0.002 nm of wavelength increment.
|
Wed Apr 13 14:29:04 2022, Carsten, Rodolfo, Sarper, David, Pierre-Michel, Max, Sebastian, Runs, Afternoon - morning shift runs 13.+14.04.
|
Changed the wavelength scan range from [B]321.62 - 321.10 nm[/B] to [B][B]321.12 - 320.60[/B] nm[/B] after one scan.

|
Sun Apr 10 15:16:19 2022, Carsten, Rodolfo, Sarper, Runs, Runs afternoon shifts 10.04
|
These are the measurement runs of the afternoon shift (10.04.).
Wavelength range is changed from 323.2 - 322.8 nm to 322.81 - 322.40 nm.
|
Thu Apr 14 17:47:55 2022, Carsten, Rodolfo, Konstantin, Sarper, Runs, Afternoon shift runs 14.04 changing the wavelength scan range
|
The new scan range is changed from [B]321.12 - 320.60 nm to 320.62 - 320.10 nm[/B]

Fri Mar 18 16:51:27 2022, Carsten, DAQ, Main DAQ /MBS error
|
MBS error "TDC data ready wait" solved. Common stop trigger (20 kHz) was missing. (according to Sebastian) |
Wed Mar 23 15:38:15 2022, Carsten, General, Not all lights in the ESR can be switched off
|
Three of the lights in the ESR cannot be switched off. It seems that these lights are now "emergency lights" (with battery?). We will need to find dark
plastik foilor similar to cover those lights during our beam time |
Thu Mar 24 17:10:33 2022, Carsten, DAQ, DAQ / MBS VUPROM TDC buffer errors
|
VUPROM TDC buffer errors potentially due to long TDC common Stop gate (>1ms from div 200).
Signal piped through coinc. unit gicv es shorter sginal (~200ns). This signal used as common stop seems to have cured the TDC buffer errors.. |
