Until now, there is no 184Hf72+ and 186Hf72+ ions. 

I added automatic shift tracking and a check for a minimum wanted power in that bin to Shahab's npz_addup.py script.
It looks for the highest bin in the projected spectrum (so after time-cut) and tracks it position. Careful, it uses the position in the very first FILE as reference. So, the ordering in the given file list affects this.

Here's Shahab's log entry about the initial script:

Created pull request in Shahabs repo:
https://github.com/xaratustrah/e0018_e0203_scripts/pull/1

Before that is accepted, find the script here:
https://github.com/mijja-koeln/e0018_e0203_scripts/blob/main/npz_addup.py


New command line options are:
  -h, --help            show this help message and exit
  -t TIME_CUT, --time-cut TIME_CUT
                        Start time as a float (optional)
  -s, --shift-track     Enable shift tracking based on strongest peak in spectrum (optional)
  -l PWR_LIMIT, --pwr-limit PWR_LIMIT
                        Set minimum power required to process file (optional)
  -v, --verbose         Print additional information (optional)


"-s" enables shift tracking and correction.

"-l" enables power limit / threshold. Only files with at least this power in the highest bin are used for summation.

"-v" prints infos abuot the tracking in each file. Optional, if you want to see how good it works.

The --time-cut option is applied in all scenarios, i.e. also before projection used for tracking.

Have fun!

This shows the spectrum of 188Hf72+ during "April06_01:00_02:00". Until April 6 2:00, the Bp = 7.918262 Tm has not been changed. 
The ntcap spectrum is from:
/data.local/G22-00018_00203/results/ntcap/iq/IQ_2025-04-05_17-43-49/0000756.iq.tdms.root


analysis settings:

2^18 samples per frame + average over 32 frame.
26.21 ms per frame
838.86 ms for 32 averaged frames

Now ESR is set to the 188Hf72+ setting.

The 188Hf72+ setting measurement starts now. Exactly the same setting like two days ago.

Tuning is finished, 186Hf is running. Sharp peaks now.

DAQ stopped with last file in RSA1-2025.04.04.17.58.49.340.tiq

Now the plan is to change one of the analyzers to narrow band recording for longer from the 245 Schotkky. 

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.

ESR setting is changed from 188Hf72+ to 186Hf72+. SIS-18 beam energy for 
this fragment is 510 MeV/u.Brho = 7.86166 Tm.
