Motion of a fusion-proton beam in a Traveling Wave Direct Energy Converter (TWDEC) is studied theoretically. Bunching of the proton beam at the modulator and periodic motion of trapped protons at the decelerator are analyzed in order to estimate adequate amplitude of traveling waves. It is shown that the traveling wave is required to have the amplitude about 1 MV for deceleration of 15 MeV protons. Orbital calculation is carried out in order to examine modulation, bunching, trapping and deceleration of the proton beam in the TWDEC. Numerical calculation shows that about 80% of the kinetic energy of the proton beam can be converted into the electricity when bunching of the beam is improved by applying multi-stage velocity modulation or continuous velocity modulation of the proton beam.
