A Ka-band (26-40 GHz) coaxial hybrid iron (CHI) wiggler ubitron amplifier experiment under construction at the Naval Research Laboratory is described. The principal goal of the experiment is to investigate the performance tradeoffs involved in the CHI configuration for high frequency amplifiers operating at low voltages with small wiggler periods. The nominal design parameters are a center frequency of 35 GHz, wiggler period of 0.75 cm, and beam voltage of approximately 150 kV. Nonlinear simulations of the interaction are presented, along with the results of magnetic field measurements performed on a prototype version of the CHI wiggler.
