Abstract :
Engineering aspects of electron and positron injection, storage and extraction in a damping ring of an injection complex are described. Symmetrical strip-line type kickers are used in quasi-traveling wave mode. A generator of a pair of negative and positive polarity pulses bases on two double pulse forming network (DPFN). Both DPFN are charged up to 50 kV using a common pulse transformer. Every DPFN is commutated by single high-voltage hydrogen thyratron. One of the thyratrons has a floating cathode. Specially designed resistors are used as kicker terminators. The circuit wave resistance is 25 Ohm, pulses duration is 80 ns, and repetition rate is up to 50 Hz
