Temperature dependence of the probability of "small heating" and total losses of ucns on the surface of fomblin oils of different molecular mass
S. M. Cherniavsky, E. V. Lychagin, A. Yu. Muzychka +5
We measured the temperature dependence of the probability of small heating and total losses of UCNs on the PFPE Fomblin Y surface with various molecular masses Mw=2800, 3300, 6500…
Temperature dependence of the probability of "small heating" and spectrum of UCNs up-scattered on the surface of Fomblin oil Y-HVAC 18/8
V. V. Nesvizhevsky, A. Yu. Voronin, A. Lambrecht +5
We performed precision measurements of the probability of small heating and spectrum of UCNs up-scattered on the surface of hydrogen-free oil Fomblin Y-HVAC 18/8 as a function of t…
UCN sources at external beams of thermal neutrons. An example of PIK reactor
E. V. Lychagin, V. A. Mityukhlyaev, A. Yu. Muzychka +5
We consider ultracold neutron (UCN) sources based on a new method of UCN production in superfluid helium (4He). The PIK reactor is chosen as a perspective example of the applicatio…
Quantum levitation of nanoparticles seen with ultracold neutrons
V. V. Nesvizhevsky, A. Yu. Voronin, A. Lambrecht +4
Analyzing new experiments with ultracold neutrons (UCNs) we show that physical adsorption of nanoparticles/nano-droplets, levitating in high-excited states in a deep and broad pote…
Quasi-specular albedo of cold neutrons from powder of nanoparticles
R. Cubitt, E. V. Lychagin, A. Yu. Muzychka +5
We predicted and observed for the first time the quasi-specular albedo of cold neutrons at small incidence angles from a powder of nanoparticles. This albedo (reflection) is due to…
Storage of very cold neutrons in a trap with nano-structured walls
E. V. Lychagin, A. Yu. Muzychka, V. V. Nesvizhevsky +3
We report on storage of Very Cold Neutrons (VCN) in a trap with walls containing powder of diamond nanoparticles. The efficient VCN reflection is provided by multiple diffusive ela…
