William Webster Hansen

Born 27 May 1909; died 23 May 1949 at age 39.American physicist who contributed to the development of radar and is regarded as the founder of microwave technology. He developed the klystron, a vacuum tube essential to radar technology (1937). Based on amplitude modulation of an electron beam, rather than on resonant circuits of coils and condensers, it permits the generation of powerful and stable high-frequency oscillations. It revolutionized high-energy physics and microwave research and led to airborne radar. The klystron also has been used in satellite communications, airplane and missile guidance systems, and telephone and television transmission. After WW II, working with three graduate students, Hansen demonstrated the first 4.5 MeV linear accelerator in 1947.
