Description
To increase sensitivity of liquid xenon (LXe) experiments to light WIMPs, the response of the LXe medium to sub-keV nuclear recoils must be characterized. We study the feasibility for an ultra-low energy nuclear-recoil yield measurement in LXe using neutron capture. The measurement strategy uses the recoil energies imparted to xenon nuclei during the de-excitation process following neutron capture, where promptly emitted γ cascades can provide the nuclei with up to 0.3 keV$_\text{nr}$ of recoil energy due to momentum conservation. In this talk we will present simulation results and the current status of the Michigan Xenon (MiX) detector, a small sub-kilogram dual-phase xenon TPC, that is being prepared to carry out this measurement.
