Abstract:
1. A method for creating an energy-compensated pulsed ion beam, said method comprising at least the following steps: creating a continuous ion beam; deflecting said continuous ion beam by a first deflector comprising of a substantially constant-amplitude oscillating electric field and directing said deflected beam so as to produce a cyclical deflection pattern at a metallic plate that includes an aperture located downstream of said first deflector; arranging said continuous ion beam to pass through said aperture at least once during each deflection cycle whereby an output pulsed beam is produced beyond said apertured metal plate; passing said pulsed beam through a second deflector where said second deflector includes a substantially constant amplitude oscillating field having amplitude and phase relationship derived from the electric fields used in said first deflector and adjusting such amplitude and phase to minimize the energy inhomogeneity introduced by said first deflector; and directing said pulsed beam leaving said second deflector through a klystron buncher.
