The NEXT experiment aims to conduct a sensitive search of the neutrinoless double beta decay ($\beta\beta0\nu$) in $^{136}$Xe, using high-pressure gas electroluminescent time projection chambers (HP-ELTPCs). Two dedicated readout planes, equipped with PMTs and SiPMs, are used to collect the primary and secondary (EL) scintillation light. While the PMTs provide the start time and the total...
LEGEND-1000 is the next-generation, ton-scale experiment searching for neutrinoless double beta decay of germanium (Ge) using p-type, high-purity germanium (Ge) detectors. It is a scaled-up project of LEGEND-200. The experiment will use 1,000 kilograms of germanium detectors enriched to over 90% ⁷⁶Ge.
The experiment has been approved and supported by the relevant agencies and will be...
The CDEX-300 is a next generation neutrinoless double beta (0νββ) decay experiment based in China Jinping underground laboratory (CJPL). CDEX-300 aims at searching the 0νββ decay of Ge-76 in the inverted neutrino mass hierarchy using high purity germanium (HPGe) detectors. We propose to build a 200 kg scale HPGe array in the liquid argon and achieve 2.5 keV (FWHM) energy resolution and 1E-4...
The LUX-ZEPLIN (LZ) experiment is a direct detection dark matter experiment that utilises a dual-phase time projection chamber (TPC) with 7 tonnes of active xenon at the Sanford Underground Research Facility in Lead, South Dakota. The experiment is primarily designed to detect interactions of dark matter in the form of weakly interacting massive particles (WIMPs), a well-motivated class of...
Over the past decade, liquid argon (LAr) has been established as a promising target for detecting Weakly Interacting Massive Particles (WIMPs), a leading dark matter candidate, due to its high particle discrimination efficiency, scalability, and intrinsic radiopurity. The Global Argon Dark Matter Collaboration (GADMC) was formed to lead a long-term research program utilizing LAr-based...
The Recoil Directionality project (ReD) within the Global Argon Dark Matter Collaboration characterized the response of a liquid argon (LAr) dual-phase Time Projection Chamber (TPC) to neutron-induced nuclear recoils, to measure the charge yield $Q_y$ at low-energy. The charge yield is a critical parameter for the experiments searching for dark matter in the form of low-mass WIMPs and...
The search for dark matter with liquid argon detectors critically depends on a precise modeling of the ionization response to nuclear recoils. We present a unified analysis of ionization data from the ReD experiment, in combination with existing measurements from DarkSide-50, ARIS, and SCENE. This combined approach allows us to place stronger constraints on electron-ion recombination and...
The measurement of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) cross-sections is crucial for advancing neutrino physics and probing for new phenomena beyond the Standard Model. A major challenge lies in mitigating low-energy backgrounds that mimic the CEvNS signal. Liquid Xenon Time Projection Chambers (LXeTPCs), having demonstrated sub-keV energy sensitivity in dark matter searches,...
We propose a new concept of a liquid xenon time projection chamber (LXeTPC) that combines fast primary scintillation (S1) with ionization-induced electroluminescence (EL) generated in liquid xenon for Positron Emission Tomography (PET) imaging. The design aims to exploit S1 for prompt timing and to use EL as a low-noise optical readout of charge to achieve precise 3D localization and improved...
The 3Dpi scanner is a Total-Body, Time of Flight, Positron Emission Tomography (PET) imaging device with silicon photomultiplier (SiPM) and a xenon-doped Liquid Argon (LAr) scintillator with the aim of ultra-low-dose imaging for pediatric and pregnant patients. The scanner has an axial field-of-view of 200 cm and consists of nine double-sided concentric rings of SiPM panels. The xenon doping...
