Design of pulse power supply for klystron and its noise characterization

At SAMEER, extensive developments are being carried out in the field of high energy electron linear accelerator technology primarily for medical applications. In linacs, electrons are accelerated to fractions of light speed and such energy is derived through interaction with high power microwaves generated by Klystron in a specialized accelerating structure. These high power RF klystrons employed as RF amplifier in turn derive this energy from high voltage pulsed dc power supply commonly called as Modulator. Currently, we have our expertise in development of 15 MV linear accelerators which requires a 6 MW high power RF Klystron. The pulse generator driving this Klystron has maximum peak power rating of 14.4 MW; average power rating of 14.68 kW and discharges 74.59 Joules of energyinto the Klystron tube during each pulse.>p/p
