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…
