Abstract : The general theory research overs a wide range of topics of interest. In regard to ubitron/free-electron laser research, work has covered a wide variety of topics. Nonlinear analyses and simulation codes have been developed (1) for short wavelength free-electron lasers driven by planar wigglers using a superposition of Gauss-Hermite optical modes, (2) for the CHI wiggler ubitron using the modes of a coaxial waveguide, and (3) for a corrugated waveguide in conjunction with a helical wiggler. Thus, the ubitron work has spanned virtually the entire range of wiggler geometries either in use at the present time or under development. The helix traveling wave tube work has included both linear analyses and nonlinear simulations for sheath helix geometry.
