As liquid xenon detectors grow in scale, novel techniques are required to maintain sufficient purity for charges to survive across longer drift paths. The Xeclipse facility at Columbia University was built to test the removal of electronegative impurities through cryogenic filtration powered by a liquid xenon pump, enabling a far higher mass flow rate than gas-phase purification through heated getters. In this paper, we present results from Xeclipse, including measured oxygen removal rates for… 

Thermodynamic Stability of Xenon-Doped Liquid Argon Detectors

Liquid argon detectors are employed in a wide variety of nuclear and particle physics experiments. The addition of small quantities of xenon to argon modifies its scintillation, ionization, and

Search for New Physics in Electronic Recoil Data from XENONnT

A blind analysis of low-energy electronic-recoil data from the XENONnT dark matter experiment sets stringent new limits on solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter.

GPU-based optical simulation of the DARWIN detector

Understanding propagation of scintillation light is critical for maximizing the discovery potential of next-generation liquid xenon detectors that use dual-phase time projection chamber technology.
