Improving of ultracold neutron traps coated with liquid helium using capillarity and electric field

To increase the storage time of ultracold neutrons (UCN) inside the material traps it is promising to cover the trap walls by liquid 4He, the material which does not absorb neutrons at all. A rough side wall of UCN trap holds the required amount of 4He by the capillary effects, but the edges of wall...
