Simple Event display

Overview of how to run a simple event display.

How it works

The main program to run a basic event diplay is the ./Display. It produces a 3D plot showing the energy depositions in the 2024 test beam geometry, with the sizes and colors corresponding to the bins' contents. It can be run be run either over a particular event in the given run, or a range. It can only be run on calibrated data, otherwise all bins will be filled with 0.

Sometimes, if run over more than 100 events, the colors are not assigned - to be debugged, the problem doesn't appear when run over a signle event.

Following options are implemented:

• common with the rest of the macros:

  • `-d` : switch to debug info with debug level 0 to n

  • `-F` : set plot extention expliticly, default is pdf

  • `-i` : input file in root format,

  • `-P` : plots directory path,

  • `-r` : name of run list file,

  • `-y` : setting year externally,

• specific for the event display:

  • `-e` : setting event number to plot, default 0,

  • `-N` : setting number of events to plot, default 1,

  • `-M` : plot only muon triggered events (in the given range)

Example of how to run it:

./Display -d 1 -i $INPUT_FILE -r $RUN_LIST -P $PLOT_DIR -e 5 [-N 10 -M]

Alternative views with projections in X,Y and Z are also provided:

CAEN data

August 2024 data

The primary script implemented for the event display is runEventDisplay_2024.sh:

bash runEventDisplay_2024.sh $USERNAME $BEAM_TYPE $EVENT_NUMBER $HOW_MANY_EVENTS [muonTrig]

where: $BEAM_TYPE can be muon, electron, hadron.

HGCROC data

November 2025 data

The primary script implemented for the event display to run it on the 2025 data is runEventDisplay_TB2025.sh .

bash runEventDisplay_TB2025.sh $USERNAME [tot,adc,full,ped] $NEVT

The 2nd option defines which of the information of the HGCROC data should be filled:

• tot shows only the ToT values

• adc shows the GetIntegratedADC() value after waveform building (i.e. max-ADC so far)

• full shows the energy in mip equivalent coming from the calibrated output

• ped shows the pedestal subtracted ADC

The last argument defines for how many events you'll be creating the event displays.
