Applications of high power induction output tubes in high intensity superconducting proton linacs

Very intense proton sources are being planned at many facilities worldwide. These facilities are based on superconducting radio frequency accelerating structures. The nature of these structures require many power sources with a peak power capability in the 1 MW range with a duty factor on the order of 10%. In the past, the conventional choice for RF power has been klystron based systems. The cost and efficiency of klystron systems has caused a number of accelerator laboratories to consider lower cost and more efficient technologies. This paper will explore the possible use of induction output tubes (IOTs) with a peak power level in the range of 1 MW as an alternative for powering high intensity superconducting proton linacs.
