This paper presents a design methodology for sheet-beam formation and solenoidal magnetic field transport. A point design for a W-band amplifier gun and beam transport is discussed. The gun topology flexibly permits adjustment of beam width to accommodate various interaction circuits while maintaining beam height. This topology has been employed in the design of a 19.5 kV, 3.6 A (1.32 mu-perv.) gun using the 3-D gun code MICHELLE in conjunction with the magnet code MAXWELL-3D.
