Abstract
Fermi National Accelerator Laboratory is undergoing an effort to upgrade the 201 MHz Proton Source system. One subset of this upgrade is addressing triode modulator reliability issues. The present system uses series-pass regulator vacuum tubes to provide pulsed voltage to the anode of a triode amplifier. A multifaceted waveform is generated including long rise and fall times, a high dv/dt step during the middle of the pulse, and a precise flat top. The shape of this waveform changes from pulse to pulse as it is part of the RF feedback control system.
