Xenon-ARgon Technology for astroparticle physics and medical applications – X-ART

Liquid argon (LAr) detectors have reached an unprecedented level of development and are now used in many areas of particle physics and astroparticles. Doping LAr with xenon can further extend the fields of application, as Xe acts as a wavelength shifter and speeds up the scintillation, keeping the scalability of LAr technology almost unchanged. For example, Xe-Ar technology can be of interest in the development of pediatric Xe-doped LAr PETs, or in the field of neutrinoless double beta decay, by mixing 136Xe-enriched Xe in LAr.
This project is dedicated to provide an extensive characterization of the Xe-Ar mixture in terms of maximum solubility, thermodynamics, and scintillation and ionization properties as a function of the Xe concentration.
