Neutron detection with a GEM

Since GEM was introduced, it has been developed in many application areas. We have developed the neutron detector with GEM coated with the converting foil. The neutron efficiency of a foil was calculated with MCNP and TRIM. The neutron efficiency of multi GEM foils was also calculated. The boron compound was coated on the drift plate, and the neutron was measured with a gas chamber installed with GEM. The process of boron-coating on GEM foil, and the stabilization of it has been under way in KAERI.
