Experiment studying one-proton emission of 69Br at FRS
Idea of the measurement (old slide. don't trust all the numbers, what we requested was not exactly what we obtained):
Description of actual setup with correct numbers - to be done!!!
Documentation
- Logbook of the experiment and preparations is here: logbook
- Files sheets and FRS logbook (experiment was divided into two runs) :
3-6 March, 2020:
data file sheet 1, see files *_0216.lmd - *_1016.lmd
FRS logbook 1, see pages 53 - 64
9-10 March, 2020:
data file sheet 2, see files *_1988.lmd - *_2284.lmd
FRS logbook 2, see pages 25 - 27
- Logbook with Si array dimensions: here
- Plan of the experiment: plan
- LISE++ file: lise file
- Files with FRS' magnet settings (parammodi): download files . There was some confusion with the name of the experiment, in these files S459 name is used.

Data
- GSI server kronos.hpc.gsi.de
Data accessible under frsgast user at /lustre/nustar/profi/s475plus
- NAS server in Opava University expert.physics.slu.cz

Server is accessible from lx-pool.gsi.de, data is at /share/keeper/gsi_2020_70br/s475plus
- On local GSI PC, ask Daria Kostyleva for information
Unpacker
- ucesb for compressed DSSD data
Under frsgast user at /u/frsgast/s475plus/upexps/202003_s474s475p with ROOT 5
To turn on correct soft versions do: . /cvmfs/csee.gsi.de/go4/501-02-ROOT5/go4login
Usage to convert:
./202003_s474s475p /path/to/lmd/file/file.lmd --ntuple=RAW,/path/to/storage/of/root/file/file.root
VERY IMPORTANT: ucesb should be compiled with correct sidped_daq.txt file. This file is an exact copy of sidped.txt, which is used by DAQ to compress files. DAQ also uses sidsig.txt for compression, but for unpacking it is not needed. Note: sidped file contails pedestal values for each strip in each detector, values there are in hex.
- Go4 for FRS data
Under profi user at /u/profi/NewGo4_2020/s474_s475 with ROOT 6 and Go4 version 6
To turn on correct soft versions do: . /cvmfs/csee.gsi.de/go4/600-00/go4login
Usage to convert (select which steps you want to convert):
go4analysis -lib libGo4UserAnalysis.so -file file_in.lmd -disable-asf -step Sort -store sort_file_out.root -enable-store -step Calibr -store calib_file_out.root -enable-store -step Analysis -enable-store -store ana_file_out.root
I suggest to copy the code, compile and use where it is more convenient, but please do not touch the version under profi!
- Note During the experiment, DSSD data was written mainly in the compressed (CMP) mode. Use ucesb to unpack CMP data. The FRS data is unpacked via Go4 as described above. For the raw DSSD data Go4 code under profi in /u/profi/s475plus/go4_siderem_frs should be used. After unpacking, both DSSD and FRS data files with TTrees should be merged together using e.g. AddFriend() method.
