Abstract

Abstract

In order to develop a 500-tonne target material-level detector physical model， the structural scheme for the Jinping neutrino detector has been proposed by drawing on the structural designs of other successfully constructed neutrino detectors. Unlike conventional structural design， the steel structure of the Jinping neutrino detector faces challenges in material selection， multifunctional load-bearing， and construction space constraints to meet the requirements of the ultra-deep underground environment and physical experiments. This paper focused on the analysis of the stainless steel structural design scheme for the Jinping neutrino detector， including the stainless steel frame， stainless steel plates， and stainless steel spherical grid shell. The results demonstrated that the stainless steel frame， plates， and spherical grid shell all met the design requirements for strength and stiffness， confirming the safety and reliability of the stainless steel structural design for the Jinping neutrino detector.
