New high count rate detectors are needed for future spallation neutron sources where large areas and high efficiency (>50%) detectors are envisaged. In this framework, GEM is one of the explored detector technologies since they feature good spatial r

Silicon neutron detectors can operate at low voltage and come with ease of fabrication and the possibility of integration of readout electronics and thus are attractive from an application point of view. In this paper, we have studied thermal neutron
