Drift Tubes 2021 and 2022 Beam Test offline analysis

The data_testbeam.xlsx file contains the details of the different configurations associated to the ROOT files used for this data analysis. The focus is on the 165 GeV/c momentum muon beam runs from 11st of November. A flag isNov2021TestBeam is used to set the condition of this beam test. IsJuly2022TestBeam is used to analyze data of July 2022 test beam summarized in run_table.xlsx.

Setup

On Bari ReCAS and in the testbeam_analysis\ directory of this repository:

$ source /cvmfs/sft.cern.ch/lcg/views/LCG_102/x86_64-centos7-gcc11-opt/setup.sh
$ source setDCDataReaderEnv.sh
$ bash compile.sh
$ bash submit_first.sh

On lxplus and in the testbeam_analysis\ directory of this repository:

$ source setDCDataReaderEnv.sh
$ bash compile.sh
$ bash submit_first.sh

where the last line of code runs in parallel the ./read_data $path_to_your_run_files $i 0 -1 $sampling $N_1 $N_2 $N_3 $N_4 $binTimeInterval $dim $cut_scale command in interactive mode or on HTcondor:

• i is the run number

• 0 -10 are the number of events to be processed (-1 to process the whole data set)

• $sampling is the sampling rate to be used in analysis

• $N_1 $N_2 $N_3 $N_4 are the cuts respectively on the signal amplitude, first and second derivatives before starting the search for electron peaks (see FindPeak-algo.C for further details)

• $binTimeInterval is the time interval (ns) starting from the beginning of the waveform in which the baseline and the rms is computed

• $dim are the waveform bins available from the data acquisition window

• $cut_scale is the threshold for electron peaks to be in the same primary ionization cluster

Instructions

These macros find voltage amplitude peaks without any filter algorithm is applied to the waveform. For each sample and each channel it is able to count how many events with an actual signal we have. Config files and executables are created to run on more than one ROOT file (not available here, too much large in size).

$ submit_second.sh

It will produce in executables\:

• executable files submit_executable_conversion*.sh per each run_*.root file that has to be converted in a root file containing histos with the most important physical variables
• config files that can be run as job in recas for accelerating the process of the histos ROOT file generation

Moreover, it will produce:

• by using the plots_oldTestBeam.txt, per each .root file in the first column, per each channel in the second column, per each event in the third column some physical quantities which are related to

1. Number of Electron peaks, First Peak Time of Arrival and Last Peak Time of arrival distributions
2. Maxima
3. Charge Integral of the wavefunction (in pC)
4. Wave functions w & w/o peak arrows
5. Number of events per each channel which passes a voltage amplitude requirement for the waveform maximum of 5 mV
6. Number of Cluster distributions
7. Time Difference between two consecutive clusters
8. Time Difference between two consecutive Electrons
9. Cluster population (Number of Electron Peaks per Primary Ionization Cluster)
