Abstract : Research on crossed-field electron devices continued. A new digital computer program for solution of the nonlinear crossed-field device equations is outlined and representative solutions for the S-band amplifier are presented. The effects of spacecharge fields in the S-band amplifier are evaluated. The studies of maximum beam convergence in crossed-field devices are extended and the range of anode voltages for which Brillouin flow can be maintained in the interaction region is determined. A theoretical analysis of phase focusing in M-type amplifiers is made indicating that beam kinetic energy can be converted to RF energy if the circuit phase velocity and interaction region electric field are properly varied. The Llewellyn-Peterson equations and density function equations are solved and discussed relative to noise transport in several models of crossed-field electron guns. (Author)
