Optomechanical Detection of Individual Gas Collisions
Yu-Han Tseng, Clarke A. Hardy, T. W. Penny +4
We experimentally demonstrate the detection of momentum transfers from individual collisions of Kr, Xe, and SF with an optically levitated nanoparticle, finding good agreement…
Optomechanical vector sensing of new forces at 6 micron separation
Gautam Venugopalan, Clarke A. Hardy, Kenneth Kohn +10
The search for new gravity-like interactions at the sub-millimeter scale is a compelling area of research, with important implications for the understanding of classical gravity an…
Characterization of CRYO ASIC for charge readout in the nEXO experiment
Z. Li, M. Yu, E. Angelico +141
nEXO is a proposed next-generation experiment searching for the neutrinoless double beta decay of Xe using a tonne-scale liquid xenon (LXe) time projection chamber (TPC). T…
A flexible test facility for liquid xenon detector development
Evan Angelico, Jacopo Dalmasson, Ralph DeVoe +6
As liquid xenon time projection chambers scale to ever-larger sizes, so too do the engineering challenges they pose. We describe a large, flexible, multipurpose test facility capab…
Ultra-sensitive radon assay using an electrostatic chamber in a recirculating system
nEXO Collaboration, A. Anker, P. A. Breur +138
Rare event searches such as neutrinoless double beta decay and Weakly Interacting Massive Particle detection require ultra-low background detectors. Radon contamination is a signif…
Sensitivity of nEXO to Xe Charged-Current Interactions: Background-free Searches for Solar Neutrinos and Fermionic Dark Matter
G. Richardson, B. G. Lenardo, D. Gallacher +135
We study the sensitivity of nEXO to solar neutrino charged-current interactions, XeCs, as well as analogous interactions predicted by m…
