Abstract :
Two types (type-A and type-B) of the S-band high-power broadband multi-beam klystrons are being developed in the Institute of Electronics, Chinese Academy of Sciences (IECAS). Type-A adopts a coil focusing system, and type-B has a Periodic Reverse Permanent Magnet (PRPM) focusing system. Five tubes have been manufactured and tested to date. Test results show that both MBKs have the RF peak output power of more than 1 MW, and the RF average output power of more than 20 kW with the 200 MHz instantaneous bandwidth. The design considerations, simulation results and test specifications will be presented in conference. The technical problems met during the development of the MBKs will also be discussed.
