Abstract

A railgun system for repetitive high-speed pellet acceleration and a steady-state pellet supply system has been developed and investigated. Using a 2 m-long railgun system, the hydrogen pellet was accelerated to 2.6 km/sec by the supplied energy of 1.7 kJ. It is expected that the hydrogen pellet can be accelerated to 3 km/sec using the present pneumatic pellet accelerator and a 2 m-long augment railgun. A screw-driven hydrogen-isotope filament extruding system has been fabricated and will be tested to examine its applicability to steady-state extrusion of the solid hydrogen-isotope filament
