We tried to convince the outside pocket to move, no success. We can hear the "hissing sound" of the pressurized air but no movement. Sergey tried to move it from the HKR, also no success. After that I tried to move it again from the Messhuette...and the "Out of tolerance" error message is gone, and the pocket seems to move. (We cannot confirm from inside because the ESR is already closed).
Guess the outside pocket got intimidated by Sergey and decided to get moving again... ;-)

We will take a bit more beam once the setting is stable, but try not to fry another detector.

19:20 The outside and inside PLEIADES detectors are both moved back into their parking positions. Shifts should continue monitoring the leakage current on the mesycontrol screens and enter the values every 2h in the Google spreadsheet:

12:00 Outside particle detector moved out to parking position again (-125 mm)

Estimation of potential gain by changing. Files from this points are going to rubbish. Potential gains are c. 20% 

22:04: The current acquisition window is recording for 2.9 s. And is not recording for 3.9 s. We are running currently with a spill cycle of 5s every repetition.

22:22 The spill cycle between each injection was changed to 4->3->2s progressively and FRS also stopped taking spills so we settled on 2s spill request.

In the morning the spill request has to be changed back to 5s when the FRS goes back into operation.

new file with the setting is

RSA01-2025.04.01.22.19.06.761.tiq

nframes = 190
lframes = 65536
navg = 1

Night shift starts with no injections from SIS! We still have triggers; we called HKR and are waiting for response.

The SIS kicker has failed again.

Since few minutes do not see any beam in the ESR (on RSAs). There is beam in SIS and injection requests from the ESR seem to be there as well.

There is no beam in the ESR since couple of minutes. According to the info from HKR, the experts started to repair the magnets (power supplies) used for extraction and transfer of the beam from SIS to ESR. It is estimated to take about 1 hour.

The SIS kicker has failed again at 08:01.
Since this has happened already few times, the experts from the on-call duty service are now looking at the problem.

Beam resumed at 16:40. 

New settings for resonators:

410: plunger stay the same
center: 411.756955 MHz


245: plunger now at 150
center: 245.507668 MHz


first files on the resonators:


RSA01-2025.04.05.18.09.08.519.tiq
RSA02-2025.04.05.18.09.09.618.tiq

new DAQ Settings for the RSAs:

414475588 （192Pb+82   at 214 harmonic）
244.03689

plunger settings: 410 MHz cavity--> 8
245MHz cavity --> 350


recording at 50 MSPS
2^16 points each frame -->  1ms per frame

Average set to: 5 frames --> total of ca. 6.5 ms per average frame

first good NPZ file from this settings on RSAs starts from 17:41

NTCAP was stopped and restarted.

NTCAP restarted with new timestamp.

The NTCAP computer and crate are switched off.
The triggers are disconnected from the RSAs, but they remain on.

NTCAP Has been restarted (we restart every day around 15:00 so data goes in a new folder)

Since there are many NPZ summer scripts around, I thought I would also share mine. This one takes advantage of the power of filelists and has a progress bar. Creating file lists gives you more control over the range of analyzed data, for example, the command:

find /data.local/G22-00018_00203/results/analyzers/RSA02 -name "RSA02-2025.04.04.01.??.??.???.tiq_spectrogram.npz" > filelist.txt

makes a file list of everything file that was produced during the second hour of the morning of the April 4th. You can fine tune the wildcards according to the time range you are interested in.


then just call the script by:

python npz_addup.py filelist.txt

you can also provide time cuts, like this:

python npz_addup.py --time-cut 0.14 filelist.txt

which will cut away first 0.14 seconds of the spectrogram. Without time cuts, it will do over the whole range.


It creates 4 type of files:

summed_spectrum.npz --> for use with RionID for PID
summed_spectrogram.npz --> for general use / analysis
summed_spectrum.png --> for general view
summed_spectrogram.png --> for detailed view

if time-cut is provided, the filenames will have a "_time_cut" suffix at the end.


Here is the link to the script:
