The NEXT-CRAB-0 Optical TPC Prototype

ORAL

Abstract

The NEXT collaboration is developing a sequence of large, high pressure xenon gas time projection chambers to search for the neutrinoless double beta decay of 136Xe. Existing NEXT detectors use a PMT energy plane and a SiPM-based topological tracking plane on opposite sides of the vessel. This talk will describe an augmentation of the NEXT concept implementing an external camera readout tracking plane via high-speed cameras and VUV image intensified optics, called NEXT-CRAB (Camera Readout and Barium Tagging). The CRAB-0 prototype at UTA aims to implement the camera readout technique at small scale, informing the optical system design for a larger demonstrator system currently under construction at Argonne National Lab. This talk will present the first results from NEXT-CRAB-0 and plans for NEXT-CRAB.
