The DarkSide-20k experiment represents the latest phase of the Global Argon Dark Matter Collaboration, leveraging expertise from previous argon-based detectors. This effort is focused on constructing a dual-phase liquid argon time projection chamber (LAr-TPC) that will deploy 100 tonnes of underground argon outfitted with silicon photomultiplier (SiPM) arrays for precise light detection....
The TESSERACT collaboration will search for dark matter particles below the proton mass through interactions with two types of novel, ultra-sensitive detectors. These detectors, SPICE and HeRALD, aim to provide leading sensitivities to low-mass dark matter candidates. In this talk I will present on the recent progress made toward reaching this goal. First, I will discuss the recent deployment...
The XLZD Collaboration is developing an international experiment to search for WIMP dark matter down to the systematic limit imposed by astrophysical neutrinos. The experiment will be based on the heritage detector designs now operating at the 10-tonne scale implemented by the XENONnT and LUX-ZEPLIN collaborations, and further informed by work being carried out by the DARWIN R&D collaboration....
We will discuss the potential benefits of xenon doping in liquid argon for dark matter search experiments. Notably, doping liquid argon with xenon at the percent level is predicted to enhance the production and collection of electroluminescence light in a dual-phase argon detector, as well as improve its spatial resolution and temporal stability. At LLNL, we have constructed a test stand...
The bubble chamber approach of looking for spin dependent interactions between fluorine and dark matter has been quite impactful so far. The PICO collaboration is in the process of deploying PICO-500, a large 250 litre chamber filled with C3F8 at SNOLAB with an scheduled start of commissioning in late 2026. We will report on the design progress and the production aspects...
WIMP dark matter particles are expected to interact with liquid xenon producing nuclear recoils (NRs). It is critical for dark matter experiments to have accurate calibration of the detector response and correct modeling of xenon microphysics. The Migdal effect theorizes that when an atom is recoiling, an electron could be emitted, leading to ionization and greater energy deposition. This...
