We have some issues with the RIO computer R4l-41 (DAQ1). We had to switch off completely twice. Only then it reacted properly. Maybe a problem with the network at about 00:00 o'clock?
  28   Fri Jun 20 06:37:51 2025 KonstantinAcceleratorPosition of contaminants
I checked the positions of the contaminants. Therefore, I drove the scrapers and observed the signal at the Schottky detector

While the vertical positions are identical for all scrapers, the horizontal positions deviate due to the dispersion in the cooler section

  22   Wed Jun 18 07:59:00 2025 Julien, KonstantinLaserPhase-offset
We recognized that the output power of the pump laser was instable when externally triggered with 200kHz (stand-bye frequency of ESR). Therefore, we changed the coarse timing offset of the pockels cell trigger compared to the flash lamp pulse from 215µs to 219.9µs. 
Thereby, the output power increased from ~600mJ to 620mJ, and the PTP stability improved from 15% to 10%. The RMS stability improved from 2% to 1.2 %. With these settings we had UV pulse energies of 20mJ.

  56   Tue Jun 24 15:44:06 2025 KonstantinDAQPhase shift in DAQ1
In the SetParameters.C file is a parameter called fPar->piPhaseOffset. It was shifted from 100 to 50 in order to see ion bunches in the pmt signal and laser pulses in the photodiode signal during the same revolution in the TDC spectrum. Note that this parameter must be taken 
into account when setting the window conditions of the arrival time in the SetConditions.C file.

current settings of PMT voltages and thresholds at the CAEN CFD:

PMT South   [HV ch2: 2700V]  [CFD ch0: 8]

PMT Middle  [HV ch1: 2850V]  [CFD ch1: 8]

PMT Nord    [HV ch3: 2850V]  [CFD ch2: 9]
  54   Mon Jun 23 18:36:39 2025 Wilfried, SimonDetectorsPMT test with LED
We tested the PMTs again, this time with an UV LED that is mounted at a window close to the XUV detector.
PMT south showed a very clear increase in count rate from about 1 to 50 Hz.
PMT mid also showed a small increase by a few Hz.
For PMT north there was no great change between LED off and on, but we think that the count rate also very slightly increased. Note, that PMT north is also the furthest away from the LED.

Also we saw a difference between single- and multi-photon events at PMT south.
  41   Sat Jun 21 18:00:49 2025 Carsten, Peter, Danyal, Kristian, Marek DetectorsPMT signals
Carsten and Kristian changed (18:00) the thresholds of PMT north and PMT middle in the ESR cave. 
See picture below. The effect is negligible. 


Carsten will now (18:05) change the channel of the pre-amp of PMT north.

  42   Sat Jun 21 21:55:18 2025 Peter, Danyal, MarekDetectorsPMT rates
We have made two foam rings (outer diameter ca. 70 mm with a thickness of 10 mm each and placed them successively underneath PMT north. 

ring 1: ID = 55 mm 
ring 2: ID = 47 mm 

Without rings we had measured ca. 20 counts per channel in a time of about 7 minutes. (1st picture below) 

With ring 1 we have measured ca. 18 counts per channel in 7 mins. 

with ring 1 and ring 2 we have measured ca. 15 counts per channel in 7 mins. (2nd picture below)

It is clear that the rate of PMT north decreases with increasing distance from the beampipe. 

At this point it is not yet clear to us if the experiment will benefit from the 2 rings. 

If the rings should be implemented, we propose to have one proper ring (20 mm high) made by the mechanical workshop.

  40   Sat Jun 21 17:00:10 2025 Carsten, Peter, Danyal, Kristian, MarekDetectorsPMT north exchanged
We noted that the dark countrate of PMT north is about 20x higher than that of PMT middle. 

We went into the ESR cave to look for stray light. 
We decided to put a black cloth over all the PMTs. 
Also we made the tubes of the N2 airflow to the PMTs black (tape around). 
This did not make a significant change. 

We exchanged PMT north (same type 9423B) to see if that made a difference. 
It did not really change either. 

PMT north = 2650 V 
PMT middle = 2700 V 

The first picture below shows the dark rates for these two voltages. 

At about 17:00 we changed the voltage of PMT north to 2700 V. 
This did not change anything. 


Carsten swapped the cables of PMT north and PMt middle (inside ESR, before the amps) at 17:14.
The second picture below shows the result of that. 
Now black and red are exchanged. 


Carsten swapped the cables back again (17:20). 
Carsten and Kristian will look at the PMT signals in the ESR cave.

  4   Wed Jun 4 16:18:57 2025 Rodolfo, SimonDetectorsPMT dark count rates
I adjusted the offsets of the amplifiers in the cave and measured the dark count rates :

PMT Model Operation Voltage Count rate (Hz)
South ET9422B Broadband -1500 V 1300
Middle ET9423B Smallband -2650 V 20
North ET9423B Smallband -2650 V 30



Also the MCP anode of the XUV detector is now connected to the amplifiers and fed to the data cable of "PMT Cu".

  55   Tue Jun 24 12:25:34 2025 CarstenDetectorsPMT behaviour - noise / PMT voltages / CFD Threshholds / CAEN Power supply (broken channel resetted)
In position North there is still the "old" 9423B PMT that draws quite some current.
On this detector threre is also some quite substantial noise. Very likely the base is not ok any more. Noise was much lesss for the other two PMTs.
Since position NORTH is the position with the largest sold angle, if there is another break from the accelerator we should exchange it against SOUTH.
It was also difficult to ramp up PMT north ; and I thought that againa channel broke (showing UnV not OVC (Overcurrent)). However, the PS is resetted if
you switch of the whole crate (aka switch the PS off). Before doing so, please ramp down the other channels slowly as intended.


Please leave the PMTs (besides you go in to exhchange the PMTs).
If you ramp pt PMT North (or the same detector at a different position), start with 2400 V and then slowly increase by steps of 50V.

Checked theresholds (but during injections, so in presence of electronic noise from injection). A further adjusted might be done later when we have measurement conditions.
(Or if we have time to exchange the PMTs).


Presently we have the following settings for CAEN:


CH1: Middle 2750 V, Thr 9
CH2: South 2700 V, Thr 7
CH3: North 2800 V, Thr 9

Final voltages and thresholds for the PMTs and particle detectors before the first scan:

Detector voltage (kV) threshold (mV) mesytec
particle detector 1.35 100 -
PMT north 2.7 10 16
PMT mid 2.65 10 16
PMT south 2.7 10 16


All other mesytec thresholds remain unchanged and can be found in entry 7.

Important note: Ch0 of the PMT power supply broke, so we moved PMT north to CH3.
Current setup:
CH1: PMT mid
CH2: PMT south
CH3: PMT north

15:45 Right now, we are waiting for stable conditions again. There are problems with both the ion source and the accumulation in SIS.

16:20 SIS and source look better now, but now ESR makes trouble. The stacking looks off and after deceleration and cooling barely any Th-ions are stored. The positions of the scrapers seem to be wrong. Carsten is trying to fix it.

The Bunching is not set properly. We do not see the ion bunch with the Photomultiplier.
