REAL TIME ELECTRONIC THERMAL NEUTRON DOSIMETER USING THERMAL NEUTRON DETECTOR FORMED OF P-MOSFET AND GADOLINIUM

摘要

PURPOSE: A real time electronic thermal neutron dosimeter is provided to achieve improved use convenience and safety, while allowing for effectiveness of real time detection of thermal neutron. CONSTITUTION: A real time electronic thermal neutron dosimeter comprises a p-type metal oxide semiconductor field effect transistor(p-MOSFET) assembly(4) mounted with a p-MOSFET chip(3) serving as an oxide layer interposed between a p-MOSFET gate electrode and a substrate; and a p-MOSFET protective cap(1) mounted on the p-MOSFET chip, and which has an inner surface coated with a gadolinium layer(2) serving as a nuclear reaction film.
