Thermal Neutron Measurements with an Unpowered, Miniature, Solid-State Device

Abstract

A prototype neutron detector has been created through modification to a commercial non-volatile flash memory device. Studies are being performed to modify this prototype into a purpose-built device with greater performance and functionality. This paper describes a demonstration of this technology using a thermal neutron beam produced by a TRIGA research reactor. With a 4x4 array of 16 prototype devices, the full widths of the beam dimensions at half maximum are measured to be 2.2x2.1 cm2.
