Am. Buyko et al., POSSIBILITY OF LOW-DENSE MAGNETIZED DT PLASMA IGNITION THRESHOLD ACHIEVEMENT IN A MAGO SYSTEM, Laser and particle beams, 15(1), 1997, pp. 127-132
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.
