Abstract

Fast kickers fed by high-voltage thyrotron generators are used for extraction of charged particles in e⁺e^- colliders and synchrotron light sources. Thyratron generators can provide a rise time not less than (30-40) nsec. It is not always enough, especially for accelerator rings of small circumference. This work describes a method to achieve short rise time pulses with the help of coaxial lines filled with ferrite rings with a nonrectangular hysteresis loop and located between the thyratron generator and fast kicker. Pulses with a rise time of (2 - 3) nsec at a level of (0.1 - 0.9) from the amplitude were achieved at a 40 nsec initial rise time of thyratron generator pulses. The length of the ferrite filled line is 800 mm
