Efficiency of klystron in % is
WebRecently SLAC has been able to achieve a klystron efficiency in excess of 45% and design information of tubes which have exhibited this efficiency is available. It must be emphasized that one of the most important features of tubes designed to operate to these specifications must be long life. WebOne-dimensional disk model simulation for klystron design Full Record Related Research Abstract In 1982, one of the authors (Okazaki), of Toshiba Corporation, wrote a one-dimensional, rigid-disk model computer program <1> to serve as a reliable design tool for the 150 MW klystron development project.
