Microwave-powered pellet accelerator

A system for fueling a tokamak includes a gyrotron for radiating microwave energy into a waveguide. Also included is a module having a deutritium-tritium (DT) fuel pellet, a diamond/sapphire window, and a pusher medium located between the pellet and window that is made of frozen deuterium (D2) and m...

Zusammenfassung:	A system for fueling a tokamak includes a gyrotron for radiating microwave energy into a waveguide. Also included is a module having a deutritium-tritium (DT) fuel pellet, a diamond/sapphire window, and a pusher medium located between the pellet and window that is made of frozen deuterium (D2) 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 a gaseous expansion of the pusher medium. This ejects the pellet from the waveguide and into the plasma of the tokamak.
