Varian's involvement with magnetic fusion energy research

This article provides an overview of the history, accomplishments, and spinoffs of over two decades of interaction between the U.S. Fusion Energy Research Program`s plasma heating scientists and Varian`s Electron Device organization; an interaction which has been mutually benficial and, as with other U.S., Industry interaction with the U.S. Fusion Research Program, has produced valuable benfits to the country`s economy in the form of spinoffs which have had positive commercial and economic benfits. Varian has had two major R&D programs for the U.S. Fusion Energy Research Program: one the gyrotron development program, emerging from work to study the feasibility of a 200 kW CW 28 GHz gyrotron for the EBT program; and the other the development of super power tetrodes for Ion Cyclotron Power Sources.
