Abstract: According to an embodiment herein, a method of fabricating (100) a proton dosimeter (200) including; filing off (104) a frontal surface of a light emitting diode (LED) (120) and a frontal surface of a light-to-frequency converter (LFC) (124); exposing a plurality of first sensitive zone (122) of the LED (120) and a plurality of second sensitive zone (123) of the LFC (124); bonding (108) the plurality of first sensitive zones (122) and the plurality of second sensitive zones (123) by acrylic glue; wrapping (110) the sensitive zone interface of the LED (120) and the LFC (124) in a metal foil (111) and a polymer tape (113); and filling a gap between the metal foil (111) and a plurality of terminal leads (115) of the LED (120) and the LFC (124) with acrylic polymer aliquots (125)

Abstract: A neutron detector includes a bulk of a neutron moderating material, a first housing consisting of or comprising a gamma ray attenuating material, a second housing consisting of or comprising a gamma ray attenuating material, a first sensor device comprising a gadolinium cover disposed in the first housing, and a second sensor device disposed in the second housing. The first sensor device and the second sensor device are each sensitive to gamma rays. The first housing and the second housing are arranged adjacent to each other in the bulk.
