Abstract

A system for fueling a plasma includes a gyrotron for radiating microwave energy into a waveguide. Also included is a module having a deuterium-tritium (DT) fuel pellet, a diamond, quartz or sapphire window, and a pusher medium located between the pellet and window that is made of frozen deuterium (D.sub.2) and metallic particles. With the module in the waveguide, the gyrotron is activated. Radiation from the gyrotron is then directed into the waveguide and through the window to cause the inducement of current in the metal particles, causing the particles to become hot. The absorbed microwave energy is then transferred to the pusher medium by conduction resulting in a gaseous expansion of the pusher medium. This ejects the pellet from the waveguide and into the plasma.
