Event Details

The Large-Area Picosecond Photo-Detector Collaboration (LAPPD) is currently developing a 20x20 cm2 , thin, planar, glass-body detector with two MCPs in a chevron geometry with 8° bias angle. With a complete detector system approximating the detector design, they have measured a gain of up to 2x107 , single-photon time-of-flight resolution of ~60 ps, differential time resolution of ~5 ps, and spatial resolution of better than 1 mm in two dimensions. LAPPD detectors are being considered in CMS for vertex separation at the LHC. Another application is to search for neutrino-less double-beta decay using fast timing to reconstruct event topology by separating directional Cherenkov and isotropic scintillation light in a liquidscintillator-based detector. Dr. Elagin will discuss a technique for extracting particle direction, and evaluate several detector advances in timing, photodetector spectral response, and scintillator emission spectra that could be used to make direction reconstruction a reality in a kiloton-scale detector.
