Section: claims

1. A hybrid indirect-drive/direct drive method for inertial confinement fusion utilizing indirect drive laser beams from a first direction and direct drive laser beams from a second direction, comprising the steps of:providing a deuterium-tritium gas fusion fuel,assembling a first indirect drive portion of a shell having a first thickness partially surrounding said deuterium-tritium gas fusion fuel,assembling a second direct drive portion of a shell having a second thickness greater than said first thickness of said first indirect drive portion of a shell partially surrounding said deuterium-tritium gas fusion fuel to complete said shell,assembling a hohlraum containing at least a portion of said deuterium-tritium gas fusion fuel and at least a portion of said first indirect drive portion of a shell in a position relative to the indirect drive laser beams,shock igniting said indirect drive portion of a shell and said deuterium-tritium gas fusion fuel using the indirect drive laser beams to produce X-rays that are directed to said indirect drive portion of a shell and said deuterium-tritium gas fusion fuel; andshock igniting said direct drive portion of a shell and said deuterium-tritium gas fusion fuel using the direct drive laser beams. 2. The hybrid indirect-drive/direct drive method for inertial confinement fusion of claim 1 further comprising the step of using a fill tube extending through said shell to inject said deuterium-tritium gas fusion fuel into said shell.
