The Dual-Phase Liquid Argon Time Projection Chamber (LArTPC) aims to open new windows of opportunity in the study of neutrinos. Dual-phase LArTPCs are one of the far detector technology options foreseen for the Deep Underground Neutrino Experiment (DUNE) at Fermilab. Dual Phase (DP) refers to the extraction of ionization electrons at the interface between liquid and gaseous argon and their...

nEXO is a next-generation experiment to search for neutrinoless double beta decay ($0\nu\beta\beta$). The nEXO detector will consist of a homogeneous time projection chamber (TPC) filled with 5 tonnes of liquid xenon enriched to 90% $^{136}$Xe. nEXO is projected to reach a $0\nu\beta\beta$ half life sensitivity of $\sim$$10^{28}$ years, which will provide a search for lepton number violating...

We describe a novel ionization signal capture and waveform digitization scheme for kiloton-scale liquid argon Time Projection Chamber (TPC) detectors. The scheme is based on a pixel-scale self-triggering ‘charge integrate/reset’ block, free-running local clocks and dynamically established data networks. The scheme facilitates detailed capture of waveforms of arbitrary complexity from a...

Liquid Argon (LAr) has a widespread use in astroparticle experiments dedicated to neutrino studies and Dark Matter searches. LAr scintillation light is produced in the far Ultraviolet (128 nm), posing technical challenges for collection and detection. While there are available multiple technologies for this task, already tested and well functioning, new solutions are being searched for. An...

As noble liquid time projection chambers grow in size, their high voltage requirements increase, and detailed, reproducible studies of dielectric breakdown and the onset of electroluminescence are needed to inform their design. The Xenon Breakdown Apparatus (XeBrA) is a 5-liter cryogenic chamber at the Lawrence Berkeley National Laboratory built to characterize high voltage behavior of liquid...

The LUX dark matter experiment has measured the nuclear recoil charge and light yields in LXe down to 0.7 keVnr and 1.1 keVnr, respectively, in situ using a D-D neutron calibration source. Improvements in the D-D calibration have been possible by incorporating pulsing technique with narrow pulses (20 us / 250 Hz). This technique allows the suppression of accidental backgrounds in D-D neutron...

The latest release of the Noble Element Simulation Technique (NEST) is presented here. Noble element target media have become common in rare event searches, and an accurate comparison model is critical for understanding and predicting signals and unwanted backgrounds. Like its predecessors, NESTv2.0 is a simulation tool written in C++ and is based heavily on experimental data, taking into...

Self-shielding in ton-scale liquid noble detectors presents a unique challenge for calibrating the detector's innermost volume. Calibration isotopes must be injected directly into the active material to reach the central volume, and they must either decay away with a short half life or be purified out. I present a summary of the LUX-ZEPLIN (LZ) calibration hardware effort at UMass Amherst in...

LZ is a next generation dark matter search experiment designed to significantly extend our sensitivity to WIMP dark matter. At the core of the LZ design is a dual-phase Xe time projection chamber (TPC) with 7 tonnes of active volume. The LZ System Test platform has been constructed at SLAC and consists of three mid-size xenon detectors that, together, test and validate the performance of...

Charged particles generate copious amounts of scintillation light in the far ultraviolet when passing through the noble elements. Directly detecting these deep UV photons is challenging, and a common technique is to employ photofluorescent compounds as wavelength-shifters to convert this scintillation light into to the visible. A number of challenges continue to present themselves in the...

LUX operated at Sanford Lab from 2013 to 2016 with a primary mission to search for dark matter using a dual-phase xenon TPC with a 250 kg target mass. It produced world-leading search results. Its data continues to be used for other rare event physics searches and to improve our understanding of the detailed behavior of Xe TPCs. Ongoing LUX analyses have significantly furthered the...

DarkSide-20k is a proposed 30-tonne fiducial mass liquid argon TPC that will perform an instrumental background-free search for WIMP dark matter. The TPC will be outfitted with 200,000 silicon photomultipliers (SiPMs) grouped into 8,280 single-channel, 25 cm$^2$ photosensors that are sensitive to single photoelectrons. We will present the cryogenic performance of the first DarkSide...

Neutrino physics are a rich field of research with many unanswered questions. To continue exploring this field, liquid argon TPCs (LArTPC) are becoming increasingly popular because of their many advantages over other detector technologies. One of the largest future long-baseline neutrino oscillation experiments, DUNE, aims to build 4 x 10kt LArTPCs as its far detector. ProtoDUNE-SP is the...

The DUNE near detector will consist of several components, one of which is the high-pressure gaseous argon TPC (HPgTPC). As a promising neutrino detection technology, it is well-suited to improve the neutrino-nucleus systematic uncertainties for the neutrino oscillation measurements. In this talk, an overview of the on-going HPgTPC R&D efforts in the U.K. and U.S. will be presented.

True three-dimensional ionization charge detection and readout of liquid argon time projection chambers has recently been demonstrated. To achieve this, a 32-channel custom readout ASIC, LArPix, was used to read out a custom pixelated TPC anode immersed in liquid argon. This talk will discuss design and architectural details that enabled low-noise, low-power digitization of the charge signal....

Operating the wire readout electronics for Liquid Nobel TPCs at cryogenic temperatures has a number of advantages. As demonstrated by the BNL group, the front-end amplifier noise is reduced both by the elimination of extra capacitance due to cables and by the improved transistor noise performance at low temperature. Digitizing and digital multiplexing in the cold is also advantageous in that...
