The first ultracold-neutron (UCN) production in superfluid helium placed in a spallation
neutron source is carried out. A UCN density of 0.7 UCN/cm 3, which can be used in …

We present the first measurements of the survival time of ultracold neutrons (UCNs) in solid
deuterium (SD 2). This critical parameter provides a fundamental limitation to the …

Ultra-Cold Neutrons (UCN) are neutrons with energies so low they can be stored in material
bottles and magnetic traps. They have been used to provide the currently most accurate …

Magnetic trapping of atomic chromium and molecular calcium monohydride Magnetic trapping
of atomic chromium and molecular calcium monohydride Abstract In this thesis, I describe two …

Progress toward a measurement of the neutron lifetime using magnetically trapped ultracold
neutrons (UCN) is reported. A monochromatic beam of 8.9 Å neutrons is produced by …

Abstract Experiments with Ultra-Cold Neutrons (UCN) can offer an order-of-magnitude
improvement in the precise measurement of neutron properties which are sensitive to …

This document is the second in a series of reports on the exciting physics that would be
accessible at Fermilab in the event of an upgraded proton source. Where the first report …

A mechanism for creating well-collimated beams of neutral particles or atoms with spins is
studied. The consideration is accomplished for a general realistic case, taking into …

In the first stage of each run of a neutron lifetime experiment, a magnetic trap is filled with
neutrons. In the second stage of each run, neutron decay events plus background events …
