Design of a high frequency miniature multi beam klystron (MBK)

This paper describes the overall design of a Ku-band 19 beam klystron amplifier. The device is designed to operate near to 2.5 KV with the total beam current of 0.5A equally distributed among its various beamlets. Two new schemes of magnetic focusing arrangement have been analyzed and experimented A block window design has been incorporated for the RF input and output. First, in-house developed codes and 1D code AJ Disk is used for initial design, later commercially available 3D simulation codes like CST-studio and Ansoft HFSS have been used for final optimization of the design.
