Abstract :
The LTD stage with following parameters was designed and tested: stored energy 14 kJ, output voltage 90 kV, current amplitude in secondary turn 0.75 MA, current rise time /spl sim/430 ns. The stage could be used as a base unit in generators driving PRS Z-pinch loads as well as in high current e-beam accelerators. As a storage elements the IK-100-0.17 capacitors are used, designed and produced by PKB of Electrohydraulics, Nikolaev, Ukraine. The multi channel, multi gap spark switches in air without of overpressure connect the capacitors to the stage circuit. The electrodes of the switch are made of a cylindrical spring, providing inductive insulation between the neighboring spark channels. A special scheme is developed for triggering the switch with large surface of the electrodes.
