According to him, the acrylic sphere is composed of 263 large spherical panels, each with a thickness of 120 millimeters.

The observatory, located 700 meters underground in Jiangmen, Guangdong province, will be used to capture and analyze neutrinos, which are tiny, near-massless particles that travel near the speed of light.
The facility consists of a stainless steel shell spanning 41 meters in diameter, an acrylic sphere measuring 35.4 meters in diameter, 20,000 metric tons of liquid scintillator and 45,000 photomultiplier tubes.
