17:12 We moved the PLEIADES detector out, both are outside now (in parking position)

We are going to enter the ESR to check on the PLEIADES pocket detectors and install a nitrogen cooling.

We are inserting both PLEIADES detectors step-wise, one by one. Main beam should not be affected too long.

first file name RSA01....17.38 onwards.

All data acquisitions (both RSAs and NTCAP) are now running.

Settings similar to the 2-photon experiment.

Central frequency: 411.742243 MHz (based on Ruijius identification for 188Hf72+)

410 MHz cavity resonance frequency tuned. motors both on 50 mm
245 MHz cavity resonance frequency tuned. motors both on 390 mm

trying to do PID with some injections:

RSAs are still on winter time. they show summer time but files have winter time.

data used for PID is range from:

RSA01-2025.03.31.20.21.13.217.tiq_spectrum.npz
...
RSA01-2025.03.31.20.53.06.492.tiq_spectrum.npz

gamma_t = 1.4

but files are not so good.

continuing PID with better / higher resolution:

RSA01-2025.03.31.21.10.54.758.tiq_spectrum.npz
...
RSA01-2025.03.31.21.12.29.106.tiq_spectrum.npz

trying to do PID....

anything from RSA01-2025.04.01.02.54.25.976.tiq onwards is good data

recording parameters:

5 MHz with 6.25 MSPS, 2.5 seconds, analyzer span 100 khz, trigger at 5%

All analyzer times are now set to summer time
file time stamps are correct

settings are in the attached pictures.

all settings are done.
any files coming after this one is good:

RSA01-2025.04.01.03.52.59.247.tiq

23:55 stop the RSAs. 

410:
last file from previous setting (harmonic=211): 2025.04.01.23.55.21.712.
new plunger position for 410 cavity: 33.5 inside and outside.
new center frequency: 410535000 Hz.

245:
harmonic didn't change, still 126.
adjusted center frequency to 243997000 Hz.

00:31 restart the RSAs.
new files from: 2025.04.02.00.31.11.796.

20:28 started NTCAP
started queqiao file transfer for RSAs only
started analyzer looper for RSAs

 

stop and delete NTCAP data from Weekend test

for now the NAS data2 bank has been flushed to make sure good operation for today's beam.
we have now 35 TB space on bank 2.

the recording will be done on the bank2 of the NAS.

There are still some junk data on bank1, which we will remove later.

has been restored.

We have been working together with IT on the speed of data transfer: with the new 10 GB interface we can now transfer data from NAS to Lustre with 400MB/s. From NAS to GPU Computer up to 700MB/s. All cables around the rack are now 10GB capable.

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:

examples are in attachment:

the ACC pattern for both experiments.

At around 9:40, ESR timeout changed from 10 s to 30 s
Triggering only on real injections.
Before that, every second injection was not real but the old one. They can be identified since they should have no "kicker" disturbance.
