Abstract
The MAGO concept using the thermonuclear target with DT gas preliminar y heating up to kiloelectronvolt range temperatures, which sufficientl y enables the reduction of requirements of the compression rate (to 10 km/s) and the compression degree (to several hundreds) of the target, is investigated. The MAGO chamber with the Laval supersonic annular n ozzle is used for plasma preheating. In this chamber magnetized plasma is accelerated up to 1000-km/s velocities and heated by collisionless shock waves. Systems with liner and magnetic compression are consider ed for the subsequent plasma compression. Energizing of a real-size sy stem can be supplied by the magnetic flux compression generators with energy 100-500 MJ. Experiments close to the threshold of ignition can be conducted proportionally in 2-3 times reduced systems. Then the ene rgy required will be 10-30 times less than in a real-size system.
