The DUNE experiment is a future long-baseline neutrino oscillation experiment aiming at mea-
suring the neutrino CP-violating phase and establishing the neutrino mass hierarchy, as well as at
a rich physics programme from supernovae over low-energy physics to beyond Standard Model
The baseline technology for the first far detector is a proven single-phase horizontal-drift liquid-
Argon TPC based on standard wire-chamber technology.
For the second far detector, a new technology, the so-called “vertical drift” TPC is currently being
developed: It aims at combining the strengths of the two technologies tested in the ProtoDUNE
cryostats at the CERN neutrino platform, the proven horizontal-drift single-phase TPC and the ambi-
tious vertical-drift dual-phase TPC, into a single design, a vertical-drift single-phase liquid-Argon
TPC using a novel perforated-PCB anode design. This design maintains excellent tracking and
calorimetry performance while significantly simplifying the complexity of the TPC construction.
This paper introduces the concept of the vertical drift TPC, presents first results from small-scale
prototypes and a first full-scale anode module, and outlines the plans for future prototypes and the
next steps towards the full second DUNE far detector.
