Repetitive generators with plasma opening switch

The peculiarities of repetitive generator using Plasma Opening Switch (POS) are considered They are: limited drive current value, gas-generation, pulsed thermal loads on units etc. The voltage sharpening with relatively low < 100 kA) current values is obtained Design solutions of repetitive generator RS-20 main units (Marx generator, pas, X-ray target) are represented allowing to increase their resources up to 10⁷ pulses and more.
