Characterization of Low-energy Ionization Signals in Silicon Detectors for the Nab Experiment
R. J. Taylor, August Mendelsohn, Arlee Shelby +22
The Nab (Neutron a b) experiment is designed to measure the beta-antineutrino angular correlation in free neutron decay with an ultimate precision goal of 0.1%, providing input…
Demonstration of 255-kV high-voltage generation with a Cavallo multiplier system
S. M. Clayton, T. M. Ito, A. Jacobs +11
Many cryogenic precision measurements require large electric fields in environments where conventional high-voltage feedthroughs are impractical. To address this, we developed a Ca…
Detection of ultracold neutrons with powdered scintillator screens
M. Krivos, N. C. Floyd, C. L. Morris +24
Zinc sulfide (ZnS:Ag) scintillators coated with a thin 10B layer are widely used for ultracold neutron (UCN) detection, but their application is limited by long decay times and sig…
A gaseous-helium cooling system for silicon detectors in the Nab experiment
Love Richburg, Noah Birge, Nadia Fomin +40
The Nab experiment aims to extract the neutron beta decay correlation coefficients 'a' and 'b'. This will be accomplished using a 7 m tall electromagnetic spectrometer which measur…
High voltage and electrode system for a cryogenic experiment to search for the neutron electric dipole moment
M. A. Blatnik, S. M. Clayton, S. A. Currie +16
The cryogenic approach to the search for the neutron electric dipole moment--performing the experiment in superfluid liquid helium--holds promise for a substantial increase in sens…
A Novel, Steerable, Low-Energy Proton Source for Detector Characterization
Nicholas Macsai, August Mendelsohn, David Harrison +7
We report on the conversion of the Manitoba II mass spectrometer into a versatile low-energy proton beam facility. This infrastructure is adaptable to any detector-under-test (DUT)…
