FIELD: acceleration engineering. SUBSTANCE: accelerator that may be used for generating nanosecond-length heavy-current electron and ion beams at high pulse repetition rate has ferromagnetic induction system in the form of set of N ferromagnetic cores carrying magnetizing turns. Each magnetizing turn has M taps disposed on either side of core. High-voltage pulses are shaped during discharge of shaping line made in the form of set of coaxial cables through magnetizing turns of induction-system ferromagnetic cores. Charge-voltage source is provided for charging coaxial cables and switch, for discharging the lines. Cable length , where epsi is relative dielectric constant of coaxial cable insulation; c is velocity of light; tau is desired length of voltage pulse across load. Total number of cables M = N2.ρcb/R, where R is load impedance; ρcb is wave impedance of single cable. Cables are disposed over Archimedes' spiral around induction system and are connected through terminations of inner electrodes to taps of magnetizing turns disposed on one side of cores. Outer electrodes are connected by means of switch to taps of magnetizing turns disposed on other side of cores. Shaping-line charge voltage source is connected to opposite terminations of interconnected inner and outer electrodes of coaxial cables. EFFECT: enhanced pulse power built up across linear induction accelerator load. 1 cl, 1 dwg
