Abstract
Liquefied-noble-gas detectors play a crucial role in direct dark-matter search and in neutrino oscillation experiments. Liquid argon (LAr) and liquid xenon produce a large amount (∼ 40000 ph/MeV) of UV scintillation photons which are usually wavelength shifted before being detected. In a liquefied-noble-gas TPC, event reconstruction is based on the collection of ionisation charge while scintillation light is used for triggering and event timing, calorimetry, and particle identification. This approach suffers from limitations in rate capabilities because of the long drift times of electrons in large-volume detectors. We propose a novel approach for the full-optical imaging of scintillation light in LAr able to provide a complete 4D event reconstruction (i.e., in space and time). A set of UV cameras based on the Coded Aperture technology and segmented photodetectors are employed. The new technique would allow to reconstruct with high accuracy and at high rate the path of charged tracks crossing the active volume of the detector. We present the results of preliminary Monte Carlo studies and we discuss the experimental plan aimed at fully addressing the technological challenges.
