Improved determination of the - angular correlation coefficient in free neutron decay with the SPECT spectrometer
M. Beck, F. Ayala Guardia, S. Baeßler +15
We report on a precise measurement of the electron-antineutrino angular correlation ( coefficient) in free neutron beta-decay from the SPECT experiment. The coefficient i…
Ultracold neutron production and up-scattering in superfluid helium between 1.1 K and 2.4 K
K. K. H. Leung, S. Ivanov, F. M. Piegsa +2
Ultracold neutrons (UCNs) were produced in a 4 liter volume of superfluid helium using the PF1B cold neutron beam facility at the Institut Laue-Langevin and then extracted to a det…
A comparison of two magnetic ultra-cold neutron trapping concepts using a Halbach-octupole array
K. Leung, S. Ivanov, F. Martin +3
This paper describes a new magnetic trap for ultra-cold neutrons (UCNs) made from a 1.2 m long Halbach-octupole array of permanent magnets with an inner bore radius of 47 mm combin…
Measuring the proton spectrum in neutron decay - latest results with aSPECT
M. Simson, F. Ayala Guardia, S. Baeßler +11
The retardation spectrometer aSPECT was built to measure the shape of the proton spectrum in free neutron decay with high precision. This allows us to determine the antineutrino el…
