<p>Thermonuclear fusion by the known technique of forming a plasma by the interaction of a laser beam with a solid target placed in a secondary vacuum with its surface at the focus of the laser beam optical system at the instant the plasma is formed, but incorporating the following features:- (a) the selection of the wavelength and flux of the laser beam so that the plasma, in accordance with the composition of the target has pre-determined temp. (T) and density (n) characteristics, (b) the selection of a target of cylindrical shape of length at least equal to the product of the speed of propagation of sound in the target and the time (t) for which the predetermined plasma characteristics must be preserved for the energy balance to be positive, (c) the maintenance of the laser flux incident on the target at a constant value and of the position of the focal plane of the laser beam optical system in the laser-radiation absorption zone of the plasma, at least for the time (t), so that the plasma characteristics (T) and (n) remain unchanged during this time.</p> |
