Options for the neutron lifetime measurements in traps

Abstract

Different geometries for the neutron lifetime measurements by the method of ultracold neutron storage in material traps and additional possibilities for the neutron storage in the magnetic storage ring are considered.

Potential of the neutron Lloyd’s mirror interferometer for the search for new interactions

“…There are also experiments on the search for the monopole-dipole interactions in which the polarized probe is an elementary particle: neutron [40,41,42,43], or atoms and nuclei [44,45], correction in [46].…”

Experimental Investigation into the Low-Molecular-Weight Fluoropolymer for the Storage of Ultracold Neutrons

“…The geometry of a vertical cylinder with an absorber at the top for varying the spectrum of stored neutrons appears to be the best in terms of maximizing the number of stored neutrons and enhancing the statistics [28]. It was found by modelling that this geometry is also the best in terms of simplicity of interpreting measurement results [29]. In the leadup to new measurements of the neutron lifetime in a material trap with the above low-temperature fluoropolymer, an experimental setup was constructed and various aspects of methodology of future studies (polymer deposition procedure, coating stability, reproducibility of the deposition results, variation in the spectrum of stored neutrons induced by a special absorber, and coating permeability) were examined.…”
