There are two known directions of work on the implementation of inertial thermonuclear fusion using Z-pinches. In the first, to achieve thermonuclear ignition, it is proposed to compress the target by indirect irradiation with Z-pinch X-ray radiation. The other direction is to compress the preheated magnetized plasma with a liner. Preheating reduces compression requirements, while magnetization reduces thermal conductivity losses and provides additional heating by α-particles even at low plasma density. This concept is being developed in the United States at the Z machine (MagLIF project). According to existing concepts, in order to achieve thermonuclear ignition in these schemes, facilities are required that can create a current pulse with an amplitude of ~ 60 MA. The most powerful facilities based on capacitor banks—the Z machine—realizes a current of up to 25 MA. The creation of facilities that are one order of magnitude more powerful than the Z machine is a matter of the future. Along with this, explosive magnetic generators (EMG) today already implement the required energy, although with much longer rise time of current pulse. The paper discusses the possibilities of using the EMG to achieve the ignition, the arising problems and ways to solve them. [ABSTRACT FROM AUTHOR] |
