High-power explosive magnetic energy sources for thermonuclear and physical applications (overview)

Abstract

High-power energy sources unavailable up to now are needed to carry out any one project on inertially confined controlled thermonuclear fusion (CTF). Considerable advances have been made in the area of explosive magnetic generators (EGG) as for their output characteristics (high power combined with high energy content). To develop the concept of magnetic cumulation proposed by A.D. Sakharov in 1951, two new approaches to increasing EMC fast operation by two orders (from tens of microseconds to tenths of microseconds) and increasing at the same time the current pulse amplitude by more than one order, were proposed at VNIIEF in the early sixties. The concept aimed at solving the CTF problem by target magnetic compression (MACO) under the effect of an fast-increasing field was proposed (1972) based on VNIIEF achievements, discussed (1976) at the USSR Academy of Sciences and published (1979). The key physical questions are analyzed, the problems to be solved are posed and the results achieved in the experiments with fast-operating high-power EMGs, fast-opening switches, transmitting lines and insulation systems are discussed here. The results obtained in experiments on liner acceleration as well as those on preliminary plasma magnetization and heating, carried out at the constructed EMGs, are discussed  More>>

The results obtained in experiments on liner acceleration as well as those on preliminary plasma magnetization and heating, carried out at the constructed EMGs, are discussed briefly. The conclusion is reached that the MACO system is the most suitable one to provide the ignition because the designing of high-power energy sources to be used in this system is practically complete and the concept itself does not need any intermediate transformations of one type of energy into another always accompanied by a decrease in total efficiency.
