Abstract

A history of lithium Collection Lens failures at lower than designed focusing strengths has led to extensive efforts to quantify the Lens loading environment and structural behavior. A comprehensive finite element analysis (FEA) model of the lithium Lens has been developed as part of these efforts and as a tool to aid in future lithium lens design improvements. The FEA model includes complete device geometry, the excitement current pulse (damped sine wave), temperature dependent electrical, thermal and structural (including strain rate dependent) material properties. Latest results, including transient electro-magnetic, thermal and structural solutions, for the currently operational lithium Lens design are presented.
