Description
After successful large-scale prototyping campaigns using the two ProtoDUNE
detectors, the DUNE collaboration plans to use the proven horizontal single-
phase liquid argon (LAr) TPC, based on standard wire-chamber technology, as
a baseline technology for its first far detector.
For the second far detector, the collaboration is prototyping a new, so-called “vertical drift” TPC, which aims at combining the best features of both ProtoDUNE
technologies: The main novelty of the detector is the anode constructed from
10 m² charge-readout plane (CRP) modules, which in turn consist of a stack of
segmented and perforated PCBs, which significantly reduce the complexity of the
assembly while maintaining fine-grained tracking and calorimetry performance.
First small-scale prototypes at CERN have shown promising results, and large-
scale prototyping is in preparation. This poster will present the design, first
results from the prototyping stages and the next steps towards the second DUNE
far detector.
