Ultracold neutron accumulation in a superfluid-helium converter with magnetic multipole reflector

O Zimmer, R Golub - Physical Review C, 2015 - APS
We analyze the accumulation of ultracold neutrons (UCNs) in a superfluid-helium converter
vessel surrounded by a magnetic multipole reflector. We solved the spin-dependent rate …

Experimental study of ultracold neutron production in pressurized superfluid helium

P Schmidt-Wellenburg, J Bossy, E Farhi, M Fertl… - Physical Review C, 2015 - APS
We investigate experimentally the pressure dependence of the production of ultracold
neutrons (UCNs) in superfluid helium in the range from saturated vapor pressure to 20 bar …

A magneto-gravitational neutron trap for the measurement of the neutron lifetime

DJ Salvat - 2015 - search.proquest.com
Neutron decay is the simplest example of nuclear beta-decay. The mean decay lifetime is a
key input for predicting the abundance of light elements in the early universe. A precise …
