A method for measuring deviation from Lambert diffuse scattering law of ultracold neutrons on material walls
P. D. Grigoriev, V. D. Kochev, V. A. Tsyplukhin +2
Modeling the motion of ultracold neutrons (UCNs) is crucial for assessing their losses, accurately measuring their lifetime, and describing other experiments. In material traps, it…
Numerical Calculation of Electric Field Enhancement in Neutron Traps with Rough Walls Coated with Superfluid Helium
V. D. Kochev, T. I. Mogilyuk, S. S. Kostenko +1
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 elect…
Loss rate of ultracold neutrons due to the absorption by trap walls in large material traps
Pavel D. Grigoriev, Vladislav D. Kochev, Victor A. Tsyplukhin +2
The most accurate neutron lifetime measurements now use the material or magnetic traps of ultracold neutrons (UCN). The precision of these experiments is determined by the accuracy…
Improving of ultracold neutron traps coated with liquid helium using capillarity and electric field
Pavel D. Grigoriev, Arseniy V. Sadovnikov, Vladislav D. Kochev +1
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 neutron…
