Magnetic booster target low velocity high yield impact fusion

A two stage impact fusion concept is proposed. In it the first booster stage is a magnetized low density DT target driven by a projectile accelerated up to ∼ 20 km/sec. The thermonuclear energy released in the booster stage is here used to drive a second stage high density target by ablative implosion, resulting in the release of large quantities of thermonuclear energy. The proposed novel concept has the potential of a near-term low-cost driver for an inertial confinement fusion reactor.
