Magnetized Plasma-Filled Waveguide: A New High-Gradient Accelerating Structure

Abstract

Electromagnetic waves confined between the metal plates of a plasma-filled waveguide are investigated. It is demonstrated that when the plasma is magnetized along the metallic plates., there exists a luminous accelerating wave propagating with a very slow group velocity. It is shown that the magnetized plasma >isolates> the metal wall from the transverse electric field, thereby reducing potential breakdown problems. Applications of the metallic plasma-filled waveguide to particle accelerations and microwave pulse manipulation are described.
