The Scintillating Bubble Chamber (SBC) collaboration is developing liquid-noble bubble chambers to detect sub-keV nuclear recoils, allowing the search for low-mass (GeV-scale) dark matter and coherent elastic neutrino-nucleus scattering from low-energy (MeV-scale) neutrinos. The scintillating bubble chamber detectors benefit from the energy reconstruction that the scintillation signal gives in...
We present the Crystal Xenon Time Projection Chamber (CXe TPC), a novel particle detector technology as a proposed upgrade to existing LXe TPCs, or as a standalone next-generation particle detector. The dominant background in current LXe dark matter searches is beta decays from radon contamination, which has proven to be ubiquitous, long-lived, and extremely soluble in liquid xenon....
The LUX-ZEPLIN (LZ) experiment is a direct detection dark matter experiment located 4,850 feet underground at the Sanford Underground Research Facility in South Dakota. The core of the detector is a dual-phase Time Projection Chamber that utilizes 7 tonnes of active liquid xenon as its target medium to search for dark matter interactions. The primary candidate of interest is the Weakly...
ICARUS is the largest Liquid Argon Time Projection Chamber (LArTPC) in operation and serves as the Far Detector of the Short Baseline Neutrino (SBN) program at Fermilab. Precise detector calibration is essential for reliable energy reconstruction and for maximizing the physics reach of the experiment. In this talk, I will describe the energy and timing calibration procedures developed at...
The Noble Liquid Test Facility (NLTF) at Fermilab is a liquid argon detector R&D facility open to the national and international HEP community. The facility consists of 4 permanent cryostats, ranging from 250L up to 3000L, open space for small open dewar testing and an optical test stand facility capable of measuring the optical properties of materials and characterizing photon detectors....
No large-scale, noble-liquid element experiment has ever reached its design electric field configuration without first encountering high-voltage phenomena (HVPs) that either require special procedures to address, or ultimately limit the ability of the experiment to measure properties of the universe. Noble-liquid detectors will only encounter harsher high-voltage challenges as they scale in...
Dual-phase liquid argon time projection chambers (LArTPCs) have a proven track record measuring keV-scale signals from light dark matter through the electron-counting (``S2-only'') channel. Enhancing their design can open the door for new, optimized searches for light dark matter, coherent elastic neutrino-nucleus scattering measurements at nuclear reactors, searches for new forces in beam...
TinyTPC is a compact Liquid Argon Time Projection Chamber (LArTPC) with a pixelated LArPix readout, used for R&D on improving energy reconstruction for low-energy events through enhanced ionization charge creation. We investigate the use of isobutylene, a photosensitive dopant with an ionization energy well-matched to argon scintillation light. Since scintillation light in LArTPCs is typically...
Noble element detectors are currently one of the most attractive technologies for rare-event search experiments, such as searches for WIMP dark matter. NEST (Noble Element Simulation Technique) is a software toolkit used to model the microphysics of xenon and argon in both gases and liquids. NEST can be used across a large range of applications, from table-top setups to multi-tonne...
