For the first time, a small dual-phase (liquid/gas) xenon time projection chamber was equipped with a top array of silicon photomultipliers for light and charge readout. Here we describe the instrument in detail, as well as the data processing and the event position reconstruction algorithms. We obtain a spatial resolution of $$\sim 1.5\,\text {mm}$$ ∼ 1.5 mm in the horizontal plane. To characterise the detector performance, we show calibration data with internal $$^{83\text {m}}\hbox {Kr}$$ 83…

The DARWIN project aims to build and operate a next-generation observatory for dark matter and neutrino physics, featuring a time projection chamber with a proposed active target of 40 t of liquid

The XeBRA platform for liquid xenon time projection chamber development

XeBRA is a flexible cryogenic platform designed to perform research and development for liquid xenon detectors searching for rare events. Its extra-large outer cryostat makes it possible to install a

Novel electron and photon recording concepts in noble-liquid detectors

We present several novel ionization-electron and scintillation-photon recording concepts in noble-liquid detectors, for future applications in particle and astroparticle physics and in other fields.

A measurement of the mean electronic excitation energy of liquid xenon

Detectors using liquid xenon as target are widely deployed in rare event searches. Conclusions on the interacting particle rely on a precise reconstruction of the deposited energy which requires

The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to

SiPM-matrix readout of two-phase argon detectors using electroluminescence in the visible and near infrared range

Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter searches to record (in the gas phase) the ionization signal induced by particle scattering in the



A dual-phase xenon TPC for scintillation and ionisation yield measurements in liquid xenon

The detector, its associated infrastructure, and the signal identification algorithm developed for processing and analysing the data are described, and measurements of the electron drift velocity at various electric fields are compared to literature values.

Characterisation of Silicon Photomultipliers for liquid xenon detectors

Silicon Photomultipliers (SiPMs) are considered as a solid-state sensor alternative to photomultiplier tubes in experiments using liquid xenon (LXe) as a radiation detection medium. The main

VUV-Sensitive Silicon Photomultipliers for Xenon Scintillation Light Detection in nEXO

Future ton-scale liquefied noble gas detectors depend on efficient light detection in the vacuum ultraviolet (VUV) range. In the past years, silicon photomultipliers (SiPMs) have emerged as a valid

Calibration of a two-phase xenon time projection chamber with a $^{37}$Ar source

We calibrate a two-phase xenon detector at 0.27 keV in the charge channel and at 2.8 keV in both the light and charge channels using a 37Ar source that is directly released into the detector. We map

Lowering the radioactivity of the photomultiplier tubes for the XENON1T dark matter experiment

The low-background, VUV-sensitive 3-inch diameter photomultiplier tube R11410 has been developed by Hamamatsu for dark matter direct detection experiments using liquid xenon as the target material.

Improved Measurements of the β-Decay Response of Liquid Xenon with the LUX Detector

The LUX experiment was based on a liquid-xenon time-projection chamber that was located on the 4,850’ level of the Sanford Underground Research Facility until it was decommissioned in 2016. In total,

Spatially uniform calibration of a liquid xenon detector at low energies using (83m)Kr.

This work presents a new method for calibration of liquid xenon (LXe) detectors, using the short-lived (83m)Kr source, which has transitions at 9.4 and 32.1 keV, and finds that at decreasing energies, the LXe light yield increases, while the amount of electric field quenching is diminished.

The physics of background discrimination in liquid xenon, and first results from Xenon10 in the hunt for WIMP dark matter

The WIMP limit set by the Xenon10 experiment in 2007 signals a new era in direct detection of dark matter, with several large-scale liquid target detectors now under construction. A major challenge

Performance of the Hamamatsu R11410 photomultiplier tube in cryogenic xenon environments
