Abstract :
Summary form only given. The rectangular grating periodic structure is a slow wave device which offers higher power, low voltage, compact Ku band amplifiers. The amplifier measurements are done using a round probe beam of 1 mm diameter from a 10 kV, 0.25 A, electron gun, confined by a 1 kG focusing solenoidal magnetic field. The axial velocity spread of the electron beam is measured using a Faraday cup energy analyzer. The beam spread depends on various factors associated with magnetic beam optics including a sensitivity to alignment of the gun magnetic flux field.
