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…
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…
Electrode Design for a Cavallo High Voltage Multiplier in a Cryogenic nEDM Experiment
Marie A. Blatnik, Steven M. Clayton, Bradley W. Filippone +4
The Cavallo multiplier [http://archive.org/details/b28771035_0003] is an electrostatic inductance machine that can generate low-noise high voltages electrically isolated from its v…
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 practical approach to calculating magnetic Johnson noise for precision measurements
N. S. Phan, S. M. Clayton, Y. J. Kim +1
Magnetic Johnson noise is an important consideration for many applications involving precision magnetometry, and its significance will only increase in the future with improvements…
A study of DC electrical breakdown in liquid helium through analysis of the empirical breakdown field distributions
N. S. Phan, W. Wei, B. Beaumont +6
We report results from a study on electrical breakdown in liquid helium using near-uniform-field stainless steel electrodes with a stressed area of 0.725 cm. The distribu…
Effect of an electric field on liquid helium scintillation produced by fast electrons
N. S. Phan, V. Cianciolo, S. M. Clayton +11
The dependence on applied electric field ( kV/cm) of the scintillation light produced by fast electrons and particles stopped in liquid helium in the temperature range…
A next-generation inverse-geometry spallation-driven ultracold neutron source
K. K. H. Leung, G. Muhrer, T. Hügle +7
The physics model of a next-generation spallation-driven high-current ultracold neutron (UCN) source capable of delivering an extracted UCN rate of around an-order-of-magnitude hig…
An apparatus for studying electrical breakdown in liquid helium at 0.4 K and testing electrode materials for the SNS nEDM experiment
T. M. Ito, J. C. Ramsey, W. Yao +14
We have constructed an apparatus to study DC electrical breakdown in liquid helium at temperatures as low as 0.4 K and at pressures between the saturated vapor pressure and 6…
Scintillation of Liquid Helium for Low-Energy Nuclear Recoils
T. M. Ito, G. M. Seidel
The scintillation properties of liquid helium upon the recoil of a low energy helium atom are discussed in the context of the possible use of this medium as a detector of dark matt…
Characterization of protonated and deuterated Tetra-Phenyl Butadiene Film in a Polystyrene Matrix
V. M. Gehman, T. M. Ito, W. C. Griffith +1
We study the effect of deuteration and annealing on the fluorescence spectrum shape and VUV to visible conversion efficiency of TPB films in a polystyrene matrix with input light f…
