PandaX液氙实验装置暗物质实验研究

Nearly a century of astronomical observations supporting the existence of dark matter has become widely accepted by the majority of scientists, though the fundamental properties of dark matter remain unknown. Direct detection of dark matter is one of the key methods to explore its nature. In recent years, significant advances in both detection techniques and physical research have been made using time projection chamber (TPC) technology based on xenon, making it the most widely discussed technology for direct dark matter detection. PandaX is one of the earliest domestic projects focused on direct dark matter detection. From the 120-kilogram PandaX-I, to the 580-kilogram PandaX-II, and now the 3.7-ton PandaX-4T detector currently in operation, PandaX has continuously improved its detection sensitivity, yielding numerous internationally influential research results. This article mainly introduces the development of the PandaX experiment, recent technological advancements, major published findings, and discusses future research plans.
