Abstract :
Here we report new concept of neutron detector with Microstructure Boron Layer. Our new Microstructure Boron Layer is developed to improve the neutron detection efficiency of boron film converter. Microstructure is constructed on aluminum substrate and enriched boron 10 is deposited for 2 to 4 μm thick. The Microstructure were combined with GlassGEM and tested in reclectometry beam line of J-PARC spallation neutron source. With this method, we aimed to increase the detection efficiency in thermal neutron with one layer of Microstructure Boron Layer converter.
