The Multi-purpose Time Projection Chamber (MTPC) prototype has been successfully developed and commissioned at the CSNS Back-n white neutron beamline.Its primary design objective focuses on precise measurement of light charged particle emissions in nuclear reaction,while maintaining versatile capabilities for multiple applications including fission cross-section determination, beam profile...
In the context of a gas-sampling Digital Hadronic Calorimeter (DHCAL), we explore the potential of using Graph Neural Networks (GNNs) for hadron energy reconstruction and Particle Identification (PID) in future collider experiments. GEANT4 was used to model a DHCAL module and generate datasets for training and testing the performance of the GNNs. The energy resolution for these hadrons is...
