## Progress report and future plan of the PandaX experiment, 2018

The PandaX (particle and astrophysical xenon) observatory uses xenon as target and detector to search for WIMP particles as well as neutrinoless double beta decay ($0\nu\beta\beta$) in ${}^{136}Xe$. Since the last IAC meeting in 2016, the PandaX-II experiment has been operated for two more years. The near future PandaX program will focus on the following three main directions:

1. Systematics and technical studies using PandaX-II detector;

2. Develop and operate a 4-ton scale multi-purpose liquid xenon experiment, PandaX-4T, to push further the dark matter search;

3. Develop and operate a 200-kg (upgradable to ton-scale) high pressure gas TPC (HpgTPC), PandaX-III, to search for $0\nu\beta\beta$ in ${}^{136}Xe$.

## Future plan of the PandaX Experiment, 2016

The PandaX observatory uses xenon as target and detector to search for WIMP particles as well as neutrinoless double beta decay ($0\nu\beta\beta$) in ${}^{136}Xe$. At present, the PandaX-II experiment is in operation in CJPL-I. The future PandaX program will pursue the following three main directions:

• Continue the operation of PandaX-II until a total of 2-year exposure;
• Develop and operate a multi-ton multi-purpose liquid xenon experiment, PandaX-xT, to push further the dark matter search;
• Develop and operate a 200 kg (upgradable to ton-scale) high pressure gas TPC (HpgTPC), PandaX-III, to search for $0\nu\beta\beta$ in ${}^{136}Xe$.
