IN-CORE SELF-POWERED RADIATION DETECTOR FOR DETERMINING THERMAL AND EPITHERMAL FLUX

摘要

9 49,129 A self-powered neutron detector in which two electrically isolated emitter electrodes are provided. The emitters are formed of different materials having differing responses to thermal and epithermal neutron flux. The separate signals generated between the separate emitters and a common collector electrode are used to determine the respective thermal and epithermal neutron fluxes for a more accurate flux mapping of the reactor core.
