IRRADIATION SHUTTER FOR TARGET INJECTION INTO A FUSION CHAMBER

摘要

A shutter for an injection mechanism that injects targets into a fusion chamber includes a rotatable cylinder rotating about its axis. The cylinder includes a top opening for allowing targets to enter the shutter and a bottom opening for allowing targets to leave the shutter. A curved passage extends between the top opening and the bottom opening. Rotational velocity of the cylinder is coordinated with the velocity of an injected target to enable the injected target to pass through the curved passage without interference, and to emerge from the bottom opening to travel into the fusion chamber. The curvature of the passage is coordinated with the rotational rate of the cylinder allows the target to pass through the shutter without interference, yet protects targets waiting to be injected into the fusion chamber from being exposed to conditions in the fusion chamber.
