Projectile Acceleration Aiming at Velocities above 9 km/s by a Compact Gas Gun [link]Paper  doi  abstract   bibtex   
Optimization conditions were studied for the conventional two-stage light-gas gun, which is a part of a three-stage light-gas gun having a preheating and filling stage. A firing test achieved a velocity of 6.2 km/s using helium as driver gas with a projectile weighing 0.6 gram. In the case of firing test using hydrogen with the same projectile mass and a piston weighing 430 gram, a velocity of 8.1 km/s was obtained. Moreover, it was found that higher velocity can be achieved using a lighter piston to increase the piston velocity. A velocity of 8.9 km/s was achieved using a piston weighing 290 gram.
