Abstract:
The use of the shockless compression conception reveals a promising method of constructing microtargets for thermonuclear fusion. Cylindrical layered systems can serve as a base. Energy input is carried out by irradiating open ends with coaxial ion beams along the length of the target. Deceleration of particles in the energy-input layer causes its intense heating and the cumulation of material from the DT layer and from the encompassing shell at the target axis. In the paper, single-cascade and two-cascade layered systems are considered. Energy-input laws for shockless compression of the effective DT region are found analytically. The analytical computations are corroborated by numerical experiments.
