Liquefied ultra-pure noble gases are typically the chosen target for neutrino and dark matter experiments. Commonly, the required grade of purity of such cryogenic liquids in terms of oxygen contamination (< 100 ppt), which makes it necessary for the Gaseous Argon (GAr) and/or the Liquid Argon (LAr) to circulate through adsorption columns filled, typically, with BASF Cu-0226S and Mol Sieve 4A...
The DARWIN project aims to build and operate a next-generation observatory for dark matter and neutrino physics, featuring a time projection chamber (TPC) with a proposed active target of 40 t of liquid xenon (LXe). Xenoscope is a full-scale vertical demonstrator for the future DARWIN detector built at the University of Zürich. Its main objective is to demonstrate electron drift over...
Low background detectors, such as those used in direct dark matter searches, require high-efficient neutron veto to reject nuclear recoil backgrounds. Gadolinium-doped polymethyl methacrylate (Gd-PMMA) has emerged as a promising solid neutron tagging material, with high hydrogen content for moderating neutrons and gadolinium content for capturing thermal neutrons and exploiting subsequent...
Photodetection systems in liquid noble element experiments often utilize external wavelength shifter films deposited over optical elements; however, this method is susceptible to issues such as loss of efficiency, cross-contamination, and mechanical and chemical stress. Our research group has developed MagLITe (Magnesium fluoride Light collection Improvement technique) to address these...
