Status and prospects of the PandaX-III experiment

Abstract

The PandaX-III experiment searches for neutrinoless double beta decay of 136Xe with a high-pressure xenon gaseous time projection chamber (TPC). Thermal-bonding Micromegas modules are used for charge collection. Benefitting from the excellent energy resolution and imaging capability, the background rate can be significantly suppressed through the topological information of events. The technology is successfully demonstrated by a prototype detector. The final detector has been constructed. In this paper, we will report the status of the PandaX-III experiment, including the construction and commissioning of the final detector, and the Micromegas-based TPC performance test in the prototype detector.
