- 요약Noble liquid detectors have a proven track record in searches for neutrino physics and dark matter searches. These include a series of world leading upper limits on WIMP-nucleon spin-independent cross sections in the GeV range, the most stringent lower limit on the neutrinoless double beta decay half life, and a detection of the elusive Coherent Elastic Neutrino Nucleus Scattering (CEvNS). This thesis is on the research and development of low-energy sensitive noble liquid detectors for nuclear recoil based physics searches. The two primary motivations for the development of such detectors are Coherent Elastic Neutrino Nucleus Scattering (CEvNS) from reactor antineutrinos, and low-mass dark matter in the few-GeV mass range. Both CEvNS and low-mass dark matter detectors need: low energy sensitivity - preferably to single-electron (SE) ionization signals, a large amount of target nuclei, and a low background. Such requirements are satisfied by both liquid xenon (LXe) and liquid argon (LAr), as detectors made from these media can be scaled to several tons and are capable of detecting few-electron signals. The choice between LAr and LXe is a trade off between higher recoil energies and higher statistics, so either detector medium may be viable. However, dual phase LXe-detectors have a large SE background after a large S2, and LAr detectors have optical properties which are, in many circumstances, not as ideal as LXe. As such, this work is a tale of two detectors. The first is a single-phase LXe detector aimed to potentially mitigate the SE background, whereas the second is a dual-phase xenon doped argon detector aimed to mitigate the issues with argon's optical properties.
