Hohlraum

In radiation thermodynamics, a Hohlraum is a cavity whose walls are in radiative equilibrium with the radiant energy within the cavity. First proposed by Gustav Kirchhoff in 1860 and used in the study
Laser Mégajoule
…intends to use the "indirect drive" approach, where the laser light is used to heat a high-Z cylinder made of some heavy metal (often gold) known as a "hohlraum". The hohlraum then gives off x-rays, which are used to heat a small fuel pellet containing a deuterium-tritium (DT) fusion fuel. Although considerable…
