Abstract
Stainless steel is widely used in the high energy physics equipment, due to its high strength, corrosion resistance and low background. Neutrino central detector (NCD) is a typical kind of high energy physics equipment. In this paper, three NCDs (SNO, Daya Bay and Borexino) are intensively introduced. Among them, Daya Bay NCD, which is the first neutrino detector in China, adopts the structure of cylindrical acrylic vessel and stainless steel tank. SNO NCD adopts the structure of an acrylic ball and a single-lay stainless steel latticed shell. Borexino chooses the combination of nylon vessel and stainless steel sphere. Subsequently, the Jiangmen Underground Observatory (JUNO) and Jinping NCD are presented. An alternative scheme of an acrylic ball supported by a double-layer stainless steel latticed shell for the JUNO is proposed and the mechanical analysis on the shell is conducted. Eventually, the design of the small model of Jinping detector is introduced.
