The ProtoDUNE detectors for the Deep Underground Neutrino Experiment are behemoths in their own right.

One of the ProtoDUNE experiment’s detectors is a single-phase neutrino detector. It will require a number of anode planes to detect the signature of a neutrino interaction in a bath of liquid argon. The University of Wisconsin is fabricating some of these anode planes. This is a glimpse at the process.

From the UK’s Science and Technology Facilities Council, Jan. 16, 2018: A UK team has just completed their first prototype anode plane assembly, the largest component of the DUNE detector, to be used in the ProtoDUNE detector at CERN.

From CERN Courier, Sept. 22, 2017: The DUNE far detector will be the largest liquid-argon neutrino detector ever built, comprising four cryostats holding 68,000 tons of liquid. Prototype detectors called protoDUNE are being built at CERN.

The construction of ProtoDUNE at CERN continues, and as you can see, it’s got a shiny, metallic interior.
