固体氘晶体中的UCN输运模拟

UCN transport simulation in solid deuterium crystals

Yu. N. Pokotilovski

摘要:

超冷中子从低温慢化剂中的提取效率关键取决于慢化剂材料的中子透明度。本文用蒙特卡罗模拟方法模拟了UCN从非理想(无序)固体氘晶体中逸出的几率。它是基于使用的关联函数描述在无序材料的密度波动,后者是从测量的非常低的中子能量总截面为这种材料推断。

英文摘要:

The extraction efficiency of ultracold neutrons from cryogenic moderators depends critically on the neutron transparency of the moderator material. The Monte Carlo simulation of the probability of the UCN going out from non-ideal (disordered) solid deuterium crystals has been performed. It was based on the use of the correlation function describing the density fluctuations in a disordered material, the latter being inferred from the measured very low neutron energy total cross sections for this material.
