A 10-MHz High-Voltage Modulator with Pulse-Width and Repetition-Rate Agility
Abstract
Requirements for control and rapid switching of the proton beam at the Los Alamos Meson Physics Facility (LAMPF) are continually revised to support accelerator upgrades and modifications. A recent upgrade required the development of a 10-MHz high-voltage modulator for an electrostatic kicker with real-time control of pulse width and repetition rate over a range of four decades. The modulator must be capable of producing a voltage pulse across a capacitive load with a rise time of <-20 ns (10%-90%). In addition the falling edge unde~shoot must be controlled to less than one part in 1000. The following paper describes in detail the circuit design philosophy, layout, and critical areas in system design.
