Manipulation of gravitational quantum states of a bouncing neutron with the GRANIT spectrometer
Benoit Clément, Stefan Baeßler, Valery V. Nesvizhevsky +9
The bouncing neutron is one of the rare system where gravity can be studied in a quantum framework. To this end it is crucial to be able to select some specific gravitational quant…
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…
Design and test of a compact and high-resolution time-of-flight measurement device for cold neutron beams
Damien Roulier, Valery Nesvizhevsky, Benoît Clément +6
A time-of-flight device was developed to characterize wavelength distribution and uniformity of a cold neutron beam. This device is very compact -- the distance of flight is c…
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…
