At CERN’s Neutrino Platform on the Laboratory’s Prévessin site in France sit two large boxes encased in a red grating. Inside these boxes are vast chambers surrounded by shiny stainless steel. The boxes are the cryostat modules of the ProtoDUNE experiment. Despite their large size, they are tiny in comparison to the future size of their successors for the Deep Underground Neutrino Experiment (DUNE), a vast neutrino experiment currently being built in the USA. The Neutrino Platform also houses an assembly station for the Tokai to Kamioka (T2K) experiment, another vast neutrino facility in Japan.
