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?)
14:00 We just enquired about the status and when beam could be back.
The current estimate is 17:00.
More work on laser aligment is required.
Estimated time: 1 hour |

Volker, David, Pierre-Michel & Danyal, Alexandre, Sebastian | General | new laser wavelength scan range 321.62 - 321.10 nm |
New wavelength scan range is 321.62 - 321.10 nm. Before the new scan range (compare old scan range in Entry 215) was applied,
the cooler settings were slightly modified. Current was changed from 50 mA to 40 mA, correction voltage was changed from 3943 V to 3948 V. Additionally, the positions
of scraper NA was changed from -10 mm to -8 mm and scraper NI from +10 mm to +8 mm.

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).
brand: ET enterprises
type: 2" photomultiplier, 9423B
High voltage: -2.45 kV (up to -3.5 kV)
spectral range: 110 - 230 nm
The power comes from an additional 2.5 kV supply.
(I have changed the cable: was CH0 before) |

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".
Before failure: ~7k-8k
Now: 3k
The stored particles in the SIS are only in the range between 1.4 and 1.7e9 |

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)
I asked Graziano Savino to check the vacuum gauges along the target side of the ESR (west side).
The gauges at the laser window sections (which we do not use here!) - NW and SW - were still on.
Volker remembered that, in the past, for the lowest dark countrate at the Cu PMT --> ALL GAUGES MUST BE SWITCHED OFF.
Graziano turned them off and Sebastian and I checked the Cu PMT rate in DAQ1.
Attached you can clearly see the difference: from 7500 cps to 400 cps.
When the Cu mirror is retracted the dark countrate is 200 cps.
Danyal
PS The slow increase in one plot is due to the fact that Graziano switched on the light in the ESR. |

Patrick | DAQ | go4 shows wrong frequencies and wavelengths |
Update (ID:194): In labview "Stop All", close labview, stop python script (ID:197), close wavemeter. Then restart wavemeter, python script, labview an mbs.
Both labview and the wavemeter software are displaying the scanned wavelength correctly (Fig. 1 & 2), but go4 shows something which looks just like a freely drifting wavelength (Fig. 3).
The Cobra set voltages are displayed correctly. |

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).

Runs after this have the right cobra set value but propably the wrong WM data until 10.04.22 12:44 (see also ID:198) |

The laser was not really properly scanned.
This was mainly a test run to see if everything was working. |

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.
We get now 17mJ UV pulse energy after SHG. Pulse energy before was 14mJ. |
