Ri = 41.5 cm for 10 ms. In this case, the toroidal field at radius R, after compression<br />

attains 12.8 T. The tokamak parameters <strong>and</strong> expected plasma parameters are<br />

given in Table I, <strong>and</strong> the cross-section of the toroidal field winding is shown in<br />

Fig. 1. They were chosen on the basis of the possibilities of pulsed energetics <strong>and</strong><br />

in order to obtain a plasma with thermonuclear parameters, in which the released<br />

thermonuclear power would be comparable to the energy loss power (Q ~ 1).<br />

In developing this design, the main emphasis was placed on the creation of a<br />

powerful infrastructure — power supply system, shielded experimental hall, control<br />

system, tritium system — of relative simplicity <strong>and</strong> cheapness of the tokamak device<br />

itself, permitting fast replacement by a new system according to the progress of<br />

physical ideas <strong>and</strong> the growth of the technical possibilities.<br />

Along the path chosen the whole complex of difficult technical problems resulting<br />

from the necessity to generate a strong fast varying field in a great volume should<br />

be solved. In doing so, a number of new, non-st<strong>and</strong>ard technical solutions have been<br />

adopted [4].<br />
