Abstract

Efficiency of Space-TWT is of prime concern along with the long life and high reliability. The collector efficiency plays a major role in determining the desired overall tube efficiency. Various collector efficiency enhancement techniques are employed. This paper describes the use and development of technology of carbon coated OFHC copper electrodes in multi-stage depressed collector for the enhancement of collector efficiency in helix space TWT.
