Thermal neutron simulation response of GEM-based detectors with the FLUKA-MC package

In the current work, we demonstrate the possibility of using the FLAIR (an advanced user friendly interface) that can be employed for building the radiation simulator via inserting the basic parameters in it. Generally, the FLAIR interface is utilized by the user for FLUKA MC package to assist in the editing of the input files, execution of the simulation code and for the visualization of the output data. The current work describes some of the features of the radiation simulator which a general user has to handle, while using the FLUKA MC code. Further it explores the basic structure of the FLAIR simulator generator. In the last section the results of a simulation test obtained for the thermal neutrons detection via Boron-coated (gas electron multiplier) GEM-detector using the FLUKA-MC code have been described. The detector efficiency ∼4.7% and ∼6.03% has been evaluated for the forward- and backward detector setup, respectively. The current simulation results have been compared with the experimental findings which reveals a close agreement. The obtained results revealed that the GEM-detector can detect the thermal neutrons efficiently.
