• We have developed railgun system since 1986 for the research on hypervelocity impacts in space. Three railguns with barrel length of 95 cm, 165 cm and 186 cm are used for the experiment. 95 cm railgun has 10 mm square bore, 165 cm and 186 cm railguns have round bore with 13 mm diameter. Projectile is polycarbonate block and its mass is 1.0-2.0g. A power supply is 6 mF capacitor bank. Total maximum energy is 300 kJ. The power supply is constituted by a 6 stage pulse forming network, a pulse transformer, a main switch and a crowbar switch. The current waveform may be controlled by varying the inductor of pulse forming network. The highest projectile velocity achieved in our institute is 4.8 km/sec.
