Explosively Driven Pulsed Power: Helical Magnetic Flux Compression Generators
At the start of the s, the need for very short and powerful electrical pulses became evident to Soviet scientists conducting nuclear fusion research. The Marx generator , which stores energy in capacitors, was the only device capable at the time of producing such high power pulses. The prohibitive cost of the capacitors required to obtain the desired power motivated the search for a more economical device.
The first magneto-explosive generators, which followed from the ideas of Andrei Sakharov , were designed to fill this role.
Magneto-explosive generators use a technique called "magnetic flux compression", which will be described in detail later. The technique is made possible when the time scales over which the device operates are sufficiently brief that resistive current loss is negligible, and the magnetic flux on any surface surrounded by a conductor copper wire, for example remains constant, even though the size and shape of the surface may change.
The simple basic principle of flux compression can be applied in a variety of different ways. Such generators can, if necessary, be utilised independently, or even assembled in a chain of successive stages: the energy produced by each generator is transferred to the next, which amplifies the pulse, and so on.

In the spring of , R. Lyudaev, E. Feoktistova, G.
Tsyrkov, and A. Chvileva undertook the first experiment with this type of generator, with the goal of obtaining a very high magnetic field. Helical generators were principally conceived to deliver an intense current to a load situated at a safe distance. They are frequently used as the first stage of a multi-stage generator, with the exit current used to generate a very intense magnetic field in a second generator. The practical realization of high performance MK-2 systems required the pursuit of fundamental studies by a large team of researchers; this was effectively achieved by , following the production of the first MK-2 generator in , and the achievement of currents over megaamperes from Sign In Don't have an account?
