A LINEAR PARTICLE ACCELERATOR APPARATUS INCLUDING A PARTICLE GUN FOR FORMING A BEAM OF PARTICLES, AN ACCELERATING SECTION ADAPTED TO BE EXCITED BY R.F. WAVE ENERGY FOR ACCELERATING THE PARTICLES TO HIGH VELOCITIES SUBSTANTIALLY AT THE SPEED OF LIGHT, A PULSE TRANSFORMER FOR OBTAINING HIGH VOLTAGE PULSES FOR APPLYING TO CERTAIN ELECTRODES WITHIN SAID PARTICLE GUN, A PULSE GENERATOR FOR DRIVING THE PRIMARY OF SAID PULSE TRANSFORMER, AND A CAPACITIVE LOAD COUPLED INTO THE SECONDARY OF SAID PULSE TRANSFORMER FOR ELIMINATING THE TENDENCY OF THE HIGH VOLTAGE PULSES TO SAG WHEREBY SUBSTANTIALLY MONOENERGETIC PARTICLES ARE OBTAINED IN THE BEAM OUTPUT OF SAID PARTICLE GUN.
