Abstract

A film of liquid helium on the surface of material traps for ultracold neutrons protects the neutrons from being absorbed by the trap walls. By using surface roughness and an electrostatic field, it is possible to maintain a helium film of sufficient thickness throughout the height of the trap. The field distribution near the tip of such wall roughness of the trap was calculated, and the effect of this field on holding the helium film was estimated.

带超流体氦涂层粗糙壁的中子捕获器中的电场增强数值计算

超冷中子材料阱表面的液氦膜可以保护中子不被阱壁吸收。通过使用表面粗糙度和静电场，可以在整个捕获器高度保持足够厚度的氦膜。我们计算了这种阱壁粗糙度顶端附近的场分布，并估算了这种场对保持氦膜的影响。
