Feasibility Study to use Neutron Capture for an Ultra-low Energy Nuclear-recoil Calibration in Liquid Xenon

Abstract

The feasibility of an ultra-low energy nuclear-recoil measurement in liquid xenon using neutron capture is investigated for a small (sub-kilogram) liquid xenon detector that is optimized for a high scintillation gain, and a pulsed neutron source. The measurement uses the recoil energies imparted to xenon nuclei during the de-excitation process following neutron capture, where promptly emitted $\gamma$ cascades can provide the nuclei with up to $0.3$ keV${}_{\text{nr}}$ of recoil energy due to conservation of momentum. A successful calibration of scintillation photon and ionization electron yields below this energy will contribute to a greater sensitivity for liquid xenon experiments in searches for light WIMPs.
