Simulation framework for the digitisation module of scintillators and its implementation in NeuLAND — •Yanzhao Wang1, Jan Mayer1, Igor Gasparic2, and Andreas Zilges1 — 1University of Cologne, Institute for Nuclear Physics — 2GSI Helmholtzzentrum für Schwerionenforschung
The New Large-Area Neutron Detector NeuLAND, as a part of the R3B experiment in FAIR, aims at providing a high detection efficiency and spatial-temporal resolution of the neutrons generated by the nuclear reaction from the high-intensity radioactive beam[1]. Simulations of the interactions between the neutrons and NeuLAND and its digitised output signals are imperative for the development of its event reconstruction algorithm.
In this talk, we are introducing a simulation framework and its implementation on the digitising module TAMEX most lately used in NeuLAND. Light yields of the scintillators are transformed into the actual energy values and time stamps of the particle interactions, taking into account multiple physical processes, such as light attenuation, PMT saturation, signal pile-up, the couplings between different PMT outputs and the variations among scintillators and digitiser channels. Additionally, the generic interface within the framework leaves a huge potential for similar implementations on different scintillation detectors in R3B.
