Experiments on a Gas Gun for Target Injection in Inertial Fusion Energy

抄録

Projectile-shooting experiments using a simple gas gun were carried out to address issues in target injection technology for fast-ignition-type inertial fusion energy. The gas gun consisted of a high-pressure gas reservoir, quick solenoid valve, and smooth-bore acceleration tube. Simple cylindrical projectiles were accelerated at room temperature by nitrogen gas and shot into a diagnostic chamber. In these experiments, we measured the flight speed, direction, and attitude of projectiles of different lengths. Longer projectiles showed better flight performance.
