Recently, ProtoDUNE has entered a pivotal stage: the filling of one of its two particle detectors with liquid argon. Filling such a detector takes almost two months, as the chamber is gigantic ...

and argon, the last forming by far the largest portion of the gas; this mixture was liquefied by causing it to flow into a bulb immersed in liquid air, and the bulk of the argon was removed as ...

LAr R&D work has continued towards characterising pixel readout with a liquid argon test stand in Sheffield and a comparison of its performance with multi-wire readout in APAs, with applications for ...

Liquid argon TPCs are a new type of neutrino detector which aims to address these issues, providing high-resolution 3D track reconstruction which can in principle provide unprecedented detail in ...
