Abstract

A self-powered neutron detector (SPND) with a neutron-sensitive emitter made of metallic hafnium is investigated. The SPND was manufactured at the National Research Center “Kurchatov Institute” and irradiated at the IR-8 reactor together with rhodium SPNDs. It is shown that, in contrast to the common SPND with a hafnium oxide emitter, this SPND produces an inertia-free signal that is only an order of magnitude smaller than that of the rhodium SPND.

VVER反应堆中含铪金属发射极的自供电中子探测器

研究了一种由金属铪制成的中子敏感发射极的自供电中子探测器（SPND）。SPND由国家研究中心“库尔恰托夫研究所”制造，并与铑SPND一起在IR-8反应堆上辐照。结果表明，与具有氧化铪发射极的普通SPND相比，该SPND产生的无惯性信号仅比铑SPND小一个数量级。

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
