ABSTRACT

High-power electrical sources are considered using powder fuels and explosives: pulse and explosive magnetohydrodynamic (MHD) generators and magnet flux cumulative (MC) generators. The powder MHD-generators are verified in field geophysical studies. Their further employment depends strongly on improvement of the combustion processes. Analysis is presented of ways to solve the problem. For the case where high-power pulses are needed with repetition frequencies of 1 to 1000 Hz, the use of explosive MHD-generators is promising. The MC-generators are particularly appropriate for superhigh-power supershort pulses for supplying vacuum diodes, railguns, electron and proton accelerators, powerful lasers, powerful microwave generators, etc. Various designs of such MC-generators are considered as well as their achievable parameters. A suggestion is made of their use in geophysics. The MC-generators are compared to the MHD-generators against their use as power supply for earth crust electromagnetic sounding and electrical prospecting.
