Abstract :
A 34 GHz peniotron, operating in the fundamental-mode of a slotted circuit, is under construction at UC Davis. The device is designed for second-harmonic interaction with the axis-encircling beam produced by a Northrop Grumman cusp gun. Recent efforts have concentrated on improving the magnetic field design and beam quality. Consequently, the cryogenic magnet of the initial design has been replaced with conventional coils and pole pieces. Measurement of the new magnet indicates that design goals for the magnetic field have been achieved and simulation of the beam predicts greatly improved quality.
