Abstract

The IREN facility, located in the Frank Laboratory of Neutron Physics at the Joint Institute for Nuclear Research, is an electron accelerator-driven source of intense pulsed neutrons with thermal and resonance energies. It is designed for the application of neutron time-of-flight spectroscopy, which is utilized for measuring neutron interaction cross sections and conducting elemental analysis through (epi)thermal and resonance neutron activation of samples. For the intended purposes, the precise determination of the neutron temperature at the irradiation positions is crucial. This report introduces a methodology for accurately determining the Maxwellian temperature (TM) of the thermal neutron distribution at the irradiation positions located on the outer wall of IREN’s neutron production target chamber.

IREN辐照位置中子温度的测定

IREN设施位于核能联合研究所的弗兰克中子物理实验室，是一个电子加速器驱动的具有热和共振能量的强脉冲中子源。它是为应用中子飞行时间光谱而设计的，用于测量中子相互作用截面，并通过（epi）热和共振中子活化样品进行元素分析。为了达到预期的目的，精确测定辐照位置的中子温度是至关重要的。本文介绍了一种精确测定IREN产中子靶室外壁辐照位置热中子分布麦克斯韦温度（TM）的方法。
