A LArTPC with Vertical Drift for the DUNE Far Detector

Résumé

The Far Detector of the Deep Underground Neutrino Experiment (DUNE) will be a large LAr detector located at a baseline of 1300 kilometers, 1.5 km deep underground. It is planned to be made up of four modules, each with a total mass of 17 kt of LAr, at least the first two of which will consist in Liquid Argon Time Projection Chambers (LArTPCs). To prove the feasibility of the LArTPC technology at the kiloton scale, the ProtoDUNE Single and Dual-Phase detectors were constructed and operated at the CERN Neutrino facility. This document describes the Vertical Drift detector concept, which is proposed to instrument the second DUNE module. It consists of a TPC where the electrons drift vertically, with a cathode suspended at mid-height, towards anodes placed at the bottom and top of the detector. The anodes would be made out of printed PCBs instead of wires, and the new disposition would allow the top readout electronics to be accessible during the lifetime of the experiment. An enhanced photo-detection system is also proposed, with the photo-sensors placed on the cryostat walls and the cathode, but posing a challenge in terms of power and signal transmission. Studies are ongoing both to overcome the technical challenges of this new design and to finalize the concept.
