Improved limits on Fierz Interference using asymmetry measurements from the UCNA experiment
Xuan Sun, E. Adamek, B. Allgeier +56
The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the -decay asymmetry parameter, , for free neutron decay. In the experiment, polarized ultracold n…
A New Cryogenic Apparatus to Search for the Neutron Electric Dipole Moment
M. W. Ahmed, R. Alarcon, A. Aleksandrova +91
A cryogenic apparatus is described that enables a new experiment, nEDM@SNS, with a major improvement in sensitivity compared to the existing limit in the search for a neutron Elect…
Final results for the neutron -asymmetry parameter from the UCNA experiment
B. Plaster, E. Adamek, B. Allgeier +91
The UCNA experiment was designed to measure the neutron -asymmetry parameter using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium w…
Cavallo's Multiplier for in situ Generation of High Voltage
Steven M. Clayton, Takeyasu M. Ito, John C. Ramsey +4
A classic electrostatic induction machine, Cavallo's multiplier, is suggested for in situ production of very high voltage in cryogenic environments. The device is suitable for gene…
Search for dark matter decay of the free neutron from the UCNA experiment: n
X. Sun, E. Adamek, B. Allgeier +57
It has been proposed recently that a previously unobserved neutron decay branch to a dark matter particle () could account for the discrepancy in the neutron lifetime observed i…
