PandaX4T

PandaX4T is a scientific collaboration focused on developing and operating a dark matter detector. The experiment aims to directly detect Weakly Interacting Massive Particles (WIMPs), which are leading candidates for dark matter. The detector utilizes a large volume of liquid xenon as its target material. When a WIMP interacts with a xenon nucleus, it is expected to produce a small amount of light and ionization. PandaX4T is designed to detect these faint signals with high sensitivity.

The PandaX experiment is located in the Jinping underground laboratory in China, which provides a deep underground environment shielding the detector from cosmic rays and other background radiation. This low-background environment is crucial for achieving the necessary sensitivity to detect rare dark matter interactions. The PandaX project has progressed through several phases, with PandaX-4T representing a significant upgrade and expansion of previous iterations. This larger detector aims to probe a broader parameter space for WIMP interactions and potentially increase the discovery potential. The research involves meticulous calibration, data analysis, and detector optimization to distinguish potential dark matter signals from background events.
