The two stage light gas guns have been used widely to study the collisions between planetesimals, from which the planets were believed to be made, meteorite impacts on the surface of the moon and planets, and high pressure states in the planetary interiors. The electromagnetic guns, especially railguns, are expected to make these researches with much higher velocity (more than 10km/sec) possible. The railgun accelerator system was set up in the Institute of Space and Astronautical Science (ISAS) in 1986,having more than 10km/sec with 1g projectile as a goal. The energy source is a 300kJ capacitor bank. The maximum velocity so far is 2.4km/sec at 108kJ with 2.4g projectile and 1.8m barrel.
