Description
The DUNE far detector consists of liquid argon time-projection chambers (LArTPCs), which allow for kiloton-scale fiducial mass necessary for rare event searches and sub-centimeter spatial resolution required to image those events with high precision. In the vertical drift LArTPC detector, a horizontal cathode bisects the fiducial volume, creating two stacked drift volumes in which ionization electrons drift upwards and downwards towards anodes at either the top or bottom, respectively. The electrons are detected by 3m x 3.4m surface area charge-sensitive anodes called Charge Readout Planes (CRPs) built out of perforated PCB layers with conductive strips, enabling reconstruction in 3D. An international DUNE collaboration R&D program, which developed CRP prototypes and tested them in LAr, successfully demonstrated excellent performance of the CRP as large-scale, low-noise detectors. This talk will present the DUNE vertical drift detector, CRP design, results from prototype testing, and considerations for building and installing 160 CRP in the DUNE vertical drift TPC.
