Yu. N. Pokotilovski, M. I. Novopoltsev, P. Geltenbort, Th. Brenner

摘要:

本文描述了一台能区为(0.05 - 2.5)$μ$ eV的中子飞行时间谱仪。该谱仪已通过测量超冷中子物理实验所必需的Al、Cu、$^{6}$、LiF、Si、Zr、聚四氟乙烯、聚乙烯和液体含氟聚合物等材料的总中子截面和微分中子截面的测试。

英文摘要:

A time-of-flight spectrometer of neutrons in the energy range (0.05 -- 2.5)$μ$eV is described. This spectrometer has been tested my measuring the total and differential neutron cross sections for a number of materials: Al, Cu, $^{6}$LiF, Si, Zr, teflon, polyethylene and liquid fluoropolymers, that are essential for experiments in the physics of ultracold neutrons.
