标题： Design and analysis of a 1-ton prototype of the Jinping Neutrino Experiment

摘要： Jinping中微子实验将对太阳中微子和地热中微子进行深入研究。 基于其他成功的地下中微子探测器，提出了Jinping探测器的两种结构方案（即圆柱形和球形方案）。 设计中的几个关键因素也进行了详细讨论。 根据物理需求，提出了Jinping实验的1吨原型。 随后，讨论了中微子探测器原型的结构设计、安装程序和机械分析。 结果表明，有机玻璃容器、不锈钢桁架和水箱上的最大Mises应力均低于强度的设计值。 探测器原型中不锈钢桁架的稳定性要求得到满足。 因此，1吨原型的结构方案是安全可靠的。 显示英文摘要

摘要： The Jinping Neutrino Experiment will perform an in-depth research on solar neutrinos and geo-neutrinos. Two structural options (i.e., cylindrical and spherical schemes) are proposed for the Jinping detector based on other successful underground neutrino detectors. Several key factors in the design are also discussed in detail. A 1-ton prototype of the Jinping experiment is proposed based on physics requirements. Subsequently, the structural design, installation procedure, and mechanical analysis of the neutrino detector prototype are discussed. The results show that the maximum Mises stresses on the acrylic vessel, stainless steel truss, and the tank are all lower than the design values of the strengths. The stability requirement of the stainless steel truss in the detector prototype is satisfied. Consequently, the structural scheme for the 1-ton prototype is safe and reliable.
