▎ 摘　　要

NOVELTY - The thermally conductive layer has a metal-based graphene nanocomposite material whose thermal conductivity relative to the metal matrix is increased by more than 20%. The metal matrix of the metal-based graphene nanocomposite material adopts a material with a half-life of a radioisotope generated after being activated by neutrons that is less than 24 hours. The metal-based graphene nanocomposite material is a copper-based graphene nanocomposite material. USE - Thermally conductive layer of target for neutron generation device (claimed) used to generate neutron wires. ADVANTAGE - The target material for a neutron generation device has high strength, good radiation damage resistance, low radioactivity after being activated by neutrons, can inhibit blistering, improve the heat dissipation performance of the target material, and extend the life of the target material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a target of a neutron generation device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a neutron capture treatment system.
