The DUNE experiment is a future long-baseline neutrino oscillation experiment aiming at measuring 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 searches. 
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 ambitious 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 seminar introduces the concept of the vertical drift TPC, presents first results from small-scale prototypes and the first full-scale anode modules, and outlines status of ProtoDUNE Vertical Drift, the final step before the leading up to the second DUNE far detector.
