Abstract
Abstract The disclosure relates to an apparatus for producing pulsed and intense relativistic electron beams which by means of linear pinch techniques are focused down to less than 2 mm diameter and preferably less than 1 mm, thereby making possible the generation of an extremely high power density on a selected target. The beams are approximately 30-nsec with a current of 40 ka when 3.5 million volts are applied to the cathode. The disclosure is also concerned with an apparatus providing for the impingement of such beams upon targets which are adapted to make possible the production of thermonuclear fusion power and the production of transuranic elements in more than microgram quantities.
