It was not worth engaging in small-scale work, but necessary to conduct the work broadly, with Russian scope. . . . It was not necessary to seek chea… - Igor Kurchatov

Physics is indebted to the founder of nuclear physics, Ernest Rutherford, for information regarding the interaction of deuterons. In one Of his last investigations Rutherford studied the nuclear reactions that occur when two deuterons collide. It was difficult to suspect at that time that the new facts discovered by him would help realize our hope of mastering the energy sources of the hot interior of the sun and distant stars that shine overhead.

On the one hand, there are the approaches that lead to stationary thermonuclear reactions, and on the other hand, those that are based on the idea of utilizing an instantaneous temperature rise in transient processes of very brief duration. However, irrespective of the way the investigation is carried out, there is one problem that is inevitably encountered; namely, the insulation of the plasma, which is heated to a high temperature, from the walls of the vessel in which it is confined, In other words, a means must be found to keep the fast particles within the plasma over a period sufficient for the particles to have a good chance to react with each other.

Inductive reactance is much larger than atomic resistance in pulsed discharges in which the current In- creases+ at a high rate. Thus, by using current and voltage oscillograms one' may find the time dependence of the inductance of the plasma column and hence determine how the radius of the column changes at various stages.
