Multi-stage depressed collector design using MICHELLE in ANALYST

A four-stage depressed collector is designed with MICHELLE using the optimization tool in ANALYST. The effect of slow or "true" secondary electrons (SSE), back-scattered primary electrons (BSE) and different geometries are studied in the modeling of multi-stage depressed collectors. Detail...

Description
Summary:A four-stage depressed collector is designed with MICHELLE using the optimization tool in ANALYST. The effect of slow or "true" secondary electrons (SSE), back-scattered primary electrons (BSE) and different geometries are studied in the modeling of multi-stage depressed collectors. Details of the design and optimization philosophy along with user settings in MICHELLE and ANALYST will be discussed. Results of a collector that was designed, built and tested at CPI, will be presented.
