Thermal neutron detection technologies alternative to 3He, featuring a rate capability matching the high flux expected at the European Spallation Source (ESS), are one of the main present challenges of neutron science.

Abstract

Thermal neutron detection technologies alternative to 3He, featuring a rate capability matching the high flux expected at the European Spallation Source (ESS), are one of the main present challenges of neutron science. A new thermal neutron detection technology was recently developed named the BAND-GEM, a Gas Electron Multiplier (GEM)-based detector provided with a borated 3D converter to reach high efficiency. In this paper the results of a count rate test performed on the BAND-GEM at the ORPHEE reactor are presented. The results show that the detector can easily reach a neutron count rate of 2 MHz/cm2 while maintaining a good linearity and it is able to reach 8 MHz/cm2 with a measurable loss of linearity η and with no sign of instability.
