Abstract
This paper describes a 700 MHz, 1 Megawatt continuous wave (CW), high efficiency klystron RF system utilized for a Free Electron Laser (FEL) high-brightness electron photoinjector (PI) [1,2]. The E2V klystron is a mod-anode tube that operates with a beam voltage of 95 kV. This klystron, operating with a 66% efficiency, requires ∼ 96 watts of input power to produce 1007 kW output. This output drives the 3rd cell of a 2 cell, π-mode cavity. Coupling is via a ridge-loaded tapered waveguide section and “dog-bone” iris. This paper will present the design of the RF, RF transport, coupling, and monitoring/protection systems that are required to support CW operations of the 100 mA cesiated, semi-porous SiC photoinjector.
