Q-Pix: Pixelated readout of kiloton scale noble element time projection chambers

The phenomenon of neutrino oscillations may provide a probe into some of the most compelling questions in particle physics. Future planned long baseline neutrino experiments, such as the Deep Underground Neutrino Experiment (DUNE), will study neutrino oscillations by analyzing interactions in multi-kiloton liquid argon time projection chambers. Critical to the success of these measurements is to reconstruct the 3D information about the neutrino interaction with high fidelity.

In this talk we will present a new and novel concept, known as Q-Pix, for measuring the ionization charge left behind when a neutrino interacts with a nuclei. This readout technique provides native 3D information and low-energy detection thresholds allowing the future neutrino experiments to see interactions at the edge of detection. This talk will provide an overview of the Q-Pix architecture, some preliminary results based on early prototypes, and outline the path ahead for realizing this new detector technology.
