Glass GEM Detector

Abstract

Here we report new concept of neutron detector with Glass GEM and Boron convertor. Glass GEM is fabricated with photo-etchable glass process. The conductivity of the substrate is efficient to avoid charge up and is suitable for high-count-rate application. Glass is also an attractive material for robust and stable detector. The Glass GEM detector is tested at J-PARC BL16, and succeed in detecting neutron at high-count-rate and low gamma-ray sensitivity.
