Noble liquid detectors are now ubiquitous in dark matter and neutrino physics experiments. The ability to purify the liquid of electronegative contaminants to the extent that electrons liberated by ionizing particles can be drifted over several meters with minimal attenuation, while maintaining the initial spatial orientation of the charge distribution, is now considered routine. With such...
An essential requirement for dark matter detection using liquid xenon (LXe) time-projection chambers is the removal of electronegative molecules, which are outgassed from detector materials and to which drifting electrons attach, reducing the observable ionization signal. Such detectors to date have relied on the continuous removal of these impurities from evaporated xenon using...
ArgonCube is a novel design for Liquid Argon Time Projection Chambers (LAr TPCs), segmenting the total detector volume into a number of electrically and optically isolated TPCs sharing a common cryostat.
For the charge-readout, a pixelated anode plane is employed, providing unambiguous 3D event reconstruction.
In order to maximise the active TPC volume a new technology is used for...
nEXO is a proposed tonne-scale experiment searching for neutrinoless double-beta decay. In its current design it will be a single-phase time projection chamber (TPC).
Particular care is given to the anode, especially a design consisting of a charge-sensitive tile is under study. A modular array of tiles can collect e$^-$ from a wide area. Since the tile provides 2d reconstruction, a TPC...
The LoLX project aims to study the properties of light emission in LXe. Investigating timing characteristics of both the scintillation and Cherenkov light, LoLX will explore the abilities of single-phase LXe detectors for particle physics and medical imaging. The first phase of the LoLX detector consists of 24 Hamamatsu VUV4 Silicon photomultipliers (SiPMs), giving a total of 96 channels...
