The design and construction of a 100 kW peak power, 2% duty, PCM focused, W‐band sheet beam klystron is discussed. The elliptical cross section beam is produced by a new electron gun design using a cylindrical cathode and a racetrack shaped focus electrode. The multi‐gap cavities produce acceptable values of R/Q and are designed to produce a uniform electric field over the width of the 12:1 aspect ratio beam. The prototype cavities are produced using normal machining, however, LIGA will be used to fabricate the cavities in production versions.
