 Mon May 9 17:14:02 2022, Carsten, DAQ, NTCAP DAQ
|
The NTCap DAQ computer in the HKR (Schottky logbook) is started, and all preparations for data taking (mounting of NAS etc.) are done.
Parameters for NTCAP DAQ will be adjusted as soon as beam is available. |

Mon May 9 17:16:34 2022, Carsten, Accelerator, Important: New ESR pattern - requies action for XUV detector in/out
|
The ESR pattern is enhanced compared to the thorium experiment by additional machines that can be used for cooling/waiting in order to optimize 208Bi yield.
As a consequence, the sub chain numbers (previous: virtuelle Beschleuniger) are changed. The new numbers still have to be dialed in into the devices in
the Messhütte and the automatic in/out of the XUV-detector tested- |

Mon May 9 19:05:17 2022, Wilfried, DAQ, Q-Switch signals + 0.5 ms and +1 ms in VUPROM
|
We have generated two additional signals which are fed into two VUPROM channels:
Q-Switch + 0.5 ms --> channel 9
Q-Switch + 1.0 ms --> channel 10

Mon May 9 19:56:41 2022, Zoran, Accelerator, status Monday evening
|
The main control room is setting up the SIS for extraction. At the moment there are 2.5E8 particles in the SIS. Later they will check the transport and
the devices for the
ESR injection. The ESR operators might (! no info available) take over later in the evening, but there will definitely be no beam for the experiment before |

Tue May 10 11:40:55 2022, Sebastian, Accelerator, still no beam @ESR
|
There is still no Beam in the ESR.
The beam is currently at TE3 - between SIS and ESR |

Tue May 10 11:59:45 2022, Simon, Christopher, Kristian, Sebastian, Laser, Labview VI checkups
|
The lower limit (to position) of the Cobra control VI has to be one increment smaller.
This means for moving from 601,95 to 601,74 the "to position" has to be 601.735.

|
It is now possible to stabilize and move the laser with both stages.
The software and hardware settings are attached.

Tue May 10 20:35:42 2022, Phillip, Wilfried, Max, Detectors, PMT Threshold
|
Since we have ions in the ring now, we looked at the PMT thresholds and the widths. In order to do so we looked at the Raw Signal directly before the CFD
and its output simultaneously. You can now set the threshold just above the noise. If the threshold is too low you will also see flat lines in the oscilloscope
when triggered on the CFD output. New values:

|
| The T-Scrapers at the electron cooler have an issue. They can't be moved in the horizontal direction using the DeviceControl. |

Tue May 10 23:10:25 2022, Sebastian, Patrick, Volker, Guy, Accelerator, T-Scraper Reloaded
|
We have established a Control to "manually" move the T-Scrapers via a "remote desktop". We can now move both scrapers in the horizontal direction too.
We are now T-scraping the ion beam for determining its position in the vertical and horizontal directions. |

Tue May 10 23:53:42 2022, Rodolfo, General, shift change
|
| The night shift took over. They are trying now to overlap the ion and laser beams. |

Wed May 11 01:09:07 2022, Patrick, Sebastian, Volker, Guy, Laser, Beam overlap
|
We overlapped the laser with the ion beam.
The ion beam positions are:

Wed May 11 03:10:55 2022, Patrick, Sebastian, Volker, Guy , Laser, Laser - bunch timing
|
We added the delay and gate generator in between the bunch trigger and the CFD to move the timing of the PMT middle signal relative to the photodiodes north
and south.
The center value of PD-North is at 19 bins, PD-South at 55 bins, the middle is therefore at 37 bins. The PMT peak should be half a revolution, ie 75 bins |

Wed May 11 07:28:39 2022, Simon, Christopher, Shahab, General, DAQ Loop for shifters
|
Procedure:
- Scanning phase ends (on LabView wait until "Idle Status" blinks. it will show e.g. 8 loops and 44 scans)
|
|
Wed May 11 03:17:14 2022, Patrick, Volker, Guy , Runs, Start laser scanning
|
Runs of the night shift. The wavelength range is 601.95 - 601.735 nm.
We started the wavemeter python script on atppc023 located in Desktop/wavemeter_Bi.
We changed the wavelength range in go4 to the actual scan range.

Wed May 11 14:48:31 2022, Konstantin, DAQ, Voltage range of the Keysight DMM changed from 10V to 1V
|
During the setup of the ion beam the voltage range of the Keysight DMM was changed from 10V to 1V. Additionally, the name of the high-voltage divider was
adjusted (this changes only the filename of the file, which is stored at the local pc decpc003). |
