World's largest acrylic sphere to be completed in Jiangmen

The installation of the world's largest acrylic sphere — a 35.4-meter-diameter acrylic sphere of the Jiangmen Underground Neutrino Observatory, is expected to be completed by the end of July.

"Previously, the world's largest acrylic sphere, which is also used in neutrino detection experiments, was 12 meters in diameter," said Tang Yuesheng, chairman of Donchamp (Jiangsu) Material Technology Co Ltd. The company based in Taizhou, Jiangsu province, is the developer and manufacturer of the acrylic sphere.
