Microwave Separator for High Energy Particle Beams

Abstract

This paper describes the design and construction of a microwave separator for high energy particle beams, following the original ideas of Panofsky and Wenzel. We used a TM₀₁₂ rectangular cavity with a Q of 15 000 and a maximum power dissipation of 1.3 Mw (megawatts). With this we could deflect electrons of 150 Mev/c momentum through ¾ in. at the final focus of our analyzing magnet. The available aperture is so small that the technique is not immediately useful, but we anticipate that it may become so at higher energies, when other methods of beam separation become unfeasible.
