Abstract
Official abstract text for this publication.
A hybrid indirect-drive/direct drive for inertial confinement fusion utilizing laser beams from a first direction and laser beams from a second direction including a central fusion fuel component; a first portion of a shell surrounding said central fusion fuel component, said first portion of a shell having a first thickness; a second portion of a shell surrounding said fusion fuel component, said second portion of a shell having a second thickness that is greater than said thickness of said first portion of a shell; and a hohlraum containing at least a portion of said fusion fuel component and at least a portion of said first portion of a shell; wherein said hohlraum is in a position relative to said first laser beam and to receive said first laser beam and produce X-rays that are directed to said first portion of a shell and said fusion fuel component; and wherein said fusion fuel component and said second portion of a shell are in a position relative to said second laser beam such that said second portion of a shell and said fusion fuel component receive said second laser beam.
First claim
Opening claim text (preview).
The invention claimed is: 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; and shock 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.
