Description
The Deep Underground Neutrino Experiment (DUNE) is a next-generation experiment designed for precision measurements of long-baseline neutrino oscillations, as well as searches for rare phenomena such as supernova neutrino bursts and proton decay. The DUNE far detector consists of liquid argon time-projection chambers (LArTPCs), which provide the large fiducial mass and high spatial resolution required for neutrino physics and rare-event searches. In the vertical drift (VD) LArTPC, a horizontal cathode divides the active volume into two drift regions, with ionization electrons drifting towards anodes located above and below the cathode. The electrons are detected by 3 m $\times$ 3.4 m Charge Readout Planes (CRPs), large-area charge-sensitive anodes based on perforated printed circuit boards with conductive strips providing three readout views for 3D reconstruction. Following the successful development and testing of CRP prototypes, the design has evolved toward a configuration suitable for large-scale production and integration. This contribution will present the current status of the CRP program, recent developments of the anode design and assembly, and results from full-scale CRP testing in the recent NP02 cold-box campaign and ProtoDUNE-VD at CERN. The experience gained from these activities provides important input for the production, qualification, and installation of the CRPs for the DUNE-VD far detector.
