Correlation of hole size in support windows with calculated yield strengths

Operating parameters of thin metal foils supported by thick Al grids in use with low energy, high beam current accelerator targets and a comparison between calculated and experimentally determined yield strengths for a series of materials and support grid hole size were investigated. Correlation between theory and experiment was excellent for foils made of Al, Ti, and Havar. Experimental tensile stress is modeled well by theoretical equations describing stress on thin circular membranes stretched to the elastic limit. (Application is in use of low energy accelerators in producing PET radiotracers for hospitals.
