A novel kind of electromagnetic launcher for the acceleration of multigram-size macroparticles, to high velocities is proposed. The novel launcher concept combines the efficiency of a gun with the much higher velocities attainable by a rocket. In the proposed concept a rocket-like projectile is launched inside a gun barrel, drawing its energy from a travelling magnetic wave. The travelling magnetic wave heats and ionizes the exhaust jet of the rocket. As a result, the projectile is propelled both by the recoil from the jet and the magnetic pressure of the travelling magnetic wave. One advantage of the proposed concept is that the exhaust jet is much longer than the rocket-like projectile permitting a much longer switching time to turn on the travelling magnetic wave. One other advantage is that the rocket-like projetile is cooled by its propellant and therefore prevented from burning up.
