Date: April 10-11, 2025
Location: Tsung-Dao Lee Institute, Shanghai, China (followed by a 1.5-day guided visit to China Jinping Lab on April 12-13)
We will hold an International Open Meeting for PandaX-xT. PandaX (Particle and Astrophysical Xenon project, https://pandax.sjtu.edu.cn/) is an experimental program that employs a series of xenon detectors to search for elusive dark matter particles and to study the fundamental properties of neutrinos. Up to now, the collaboration has constructed and operated three generations of experiments, PandaX-I, PandaX-II, and PandaX-4T, with active target masses of 120 kg, 580 kg, and 3.7 tonnes, respectively, producing many results at the forefront of dark matter search and neutrino studies.
The PandaX collaboration is also preparing for the next phase, PandaX-xT, a multi-ten-tonne liquid xenon, ultra-low background, and general-purpose observatory. The full-scaled PandaX-xT contains a 43-t liquid xenon active target, opening up new windows of discovery in dark matter, Majorana neutrinos, low-energy astrophysical neutrinos, and other ultra-rare interactions. PandaX-xT may seek further upgrades utilizing isotopic separation of natural xenon. The published conceptual design of PandaX-xT can be found at https://arxiv.org/pdf/2402.03596.
The goal of this open meeting is to discuss the physics potentials of PandaX-xT, the design of the observatory, and the status of the development of various subsystems including:
- Experimental hall infrastructure
- Outer veto detector
- Inner veto detector
- Low background Cryostat
- Time Projection Chamber
- Photosensors, Cold PCBs, and Cabling
- Readout electronics
- Data-acquisition and Online System
- Liquid xenon storage and transfer
- Cryogenics and Re-circulation
- Distillation System
- Calibration System
- Slow Control and Offline Computing
At this open meeting, we would also like to discuss forming a PandaX-xT international consortium, which may incubate a formal international PandaX-xT collaboration. Participants are encouraged to submit abstracts for talks to present their interests and potential contributions on topics related to PandaX-xT. Prior registration will be required to participate.
To facilitate international visitors, a week-long academic program will also be arranged in the Tsung-Dao Lee Institute in Shanghai around the meeting. You are welcome to give seminars and discuss in-depth with local people.
For confirmed international participants, we will cover the domestic round trip and the accommodation from Shanghai to CJPL. We may be able to offer some support to Shanghai's local expenses for international participants. Depending on the actual number of people, we may need to charge a registration fee.
