Abstract
In a system and method for controlling energy deposition on a surface of an Inertial Confinement Fusion (ICF) target when imploding. Providing one or more volume absorber/radiators to absorb the incident beam and reradiate x-ray radiation within the hohlraum containing the ICF target. Varying the reflectivity of the inner wall of the hohlraum wall or outer surface of the ICF target. Further suppressing non-uniformities in the x-ray radiation emitted from the one or more volume absorber/radiators upon one or more materials located on an outer surface of the ICF target or inner surface of said hohlraum.

A system for controlling energy deposition on a surface of an Inertial Confinement Fusion (ICF) target when imploding, the system comprising:
- a hohlraum;
- one or more openings within said hohlraum to receive an incident beam;
- one or more volume absorber/radiators, located within said hohlraum and positioned to align in a one-to-one correspondence with each of the openings of said hohlraum, wherein the one or more volume absorber/radiators absorb and reradiate the incident beam as x-ray radiation;
- an ICF target located within said hohlraum;
- and
- one or more materials located on an outer surface of said ICF target or inner surface of said hohlraum, wherein said one or more materials vary across the outer surface of said ICF target or inner surface of the hohlraum.
A method of controlling energy deposition on a surface of an Inertial Confinement Fusion (ICF) target when imploding, the method comprising:
- inserting an ICF target within a hohlraum;
- providing one or more openings within said hohlraum to receive an incident beam;
- providing one or more volume absorber/radiators within said hohlraum and positioned in a one-to-one correspondence with each of the openings of said hohlraum;
- receiving the incident beam upon the one or more volume absorber/radiators;
- absorbing the incident beam and reradiating x-ray radiation within said hohlraum;
- accelerating inwardly a shell of said ICF target when hit by said x-ray radiation;
- compressing a fuel region within said shell of said ICF target by the inward acceleration of said shell;
- and
- suppressing non-uniformities in the x-ray radiation emitted from the one or more volume absorber/radiators upon one or more materials located on an outer surface of said ICF target or inner surface of said hohlraum, wherein said one or more materials vary across the outer surface of said ICF target or inner surface of the hohlraum.
