The S-band transmitter design for the Institute of Accelerating Systems and Applications racetrack microtron

A high-power CW (continuous-wave) source, at 2380 MHz, for the IASA (Institute of Accelerating Systems and Applications), (Athens, Greece), Microtron is based on the CPI (Communications and Power Industries) type VKS-8270 multi-cavity klystron. The high-level DC power conditioning for the klystron uses an existing high-voltage transformer-rectifier (HVPS) and variable-voltage transformer (VVT), designed to operate from 60 Hz power, whereas the local power is at 50 Hz. Other features include a new electronic crowbar system and high-speed primary-power disconnect.
