This software aims to simulate a pixelated Liquid Argon Time Projection Chamber using LArPix. It consists of a set of highly-parallelized algorithms implemented on the CUDA architecture.

The software takes as input a dataset containing segments of deposited energy in the detector, generated with a Geant4 wrapper called edep-sim. The output of edep-sim is in the ROOT format and must be converted into HDF5 to be used by larnd-sim. To this purpose we provide the cli/dumpTree.py script.

larnd-sim simulates both the scintillation light acquired by the light sensors and the charge induced on the pixels. The output consists of a list of packets in the LArPix HDF5 format for the charge readout and of a list of waveforms for the light readout.
