Comparative measurements of DC electrical breakdown distributions in liquid nitrogen, liquid helium, and liquid argon
N. S. Phan, S. M. Clayton, R. Gautam +4
We present a comparative study of DC electrical breakdown in liquid nitrogen, liquid helium, and liquid argon using a common cryostat, electrode assembly, voltage-ramp protocol, an…
Axion-Like Particle Search with a Hybrid Cherenkov-Scintillation Detector
A. A. Aguilar-Arevalo, S. Biedron, J. Boissevain +43
This analysis presents the first proof-of-concept search for axion-like particles (ALPs) using a hybrid Cherenkov-scintillation detector at a beam-dump facility. The work is based…
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…
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…
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…
Measurement of the Liquid Argon Scintillation Pulse Shape Using Differentiable Simulation in the Coherent CAPTAIN-Mills Experiment
A. A. Aguilar-Arevalo, S. Biedron, J. Boissevain +42
The Coherent CAPTAIN-Mills (CCM) experiment is a liquid argon (LAr) light collection detector searching for MeV-scale neutrino and Beyond Standard Model physics signatures. Two hun…
First Event-by-Event Identification of Cherenkov Radiation from Sub-MeV Particles in Liquid Argon
A. A. Aguilar-Arevalo, S. Biedron, J. Boissevain +42
This Letter reports the event-by-event observation of Cherenkov light from sub-MeV electrons in a high scintillation light-yield liquid argon (LAr) detector by the Coherent CAPTAIN…
