PandaX: Particle and Astrophysical Xenon Experiments

PandaX is designed to build and operate a ton-scale liquid xenon experiment to search elusive dark matter particles and neutrinoless double beta decay.

PandaX-II is a dark matter direct detection experiment equipped with a half-ton scale dual-phase time projection chamber (TPC). The PandaX-II experiment started since Oct 2014 with the detector installation at CJPL, followed by about one year of engineering runs and test. The commissiong run started on Nov 22, 2015.

Combining the data from the comissioning run and the first physics run, PandaX-II obtained the most stringent upper limits on the SI WIMP-nucleon cross sectiones for WIMPs with masses between 5 and 1000 GeV.
