标题： Numerical Calculation of Electric Field Enhancement in Neutron Traps with Rough Walls Coated with Superfluid Helium

摘要： 液态氦在材料表面形成的薄膜可以捕获超冷中子，保护中子不被捕集器壁吸收。 通过使用表面粗糙度和静电场，可以在捕集器的高度范围内保持足够厚度的氦膜。 计算了捕集器壁粗糙度尖端附近的电场分布，并估算了该电场对保持氦膜的作用。 显示英文摘要

摘要： 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.
