Helical cascade FCG powered by piezogenerator

The cascade FCGs with the high energy gain are defined as the separate FCG connected with each other by means of transformers and operating in series. The high energy gain systems consist of helical generators connected with each other by step-up transformers. For the power source of the first cascade the explosive piezogenerator (EPG) is more preferable. EPG and FCG are well compatible in the operating principle and electrotechnical parameters. In the present paper the results of testing the two-cascade system of helical FCG with the explosive piezogenerator as a primary source are adduced. The system has comparatively small dimensions and is intended to achieve the energy up to /spl sim/0.5 MJ in the load.
