hohlraum

An experimental source of blackbody radiation in the form of an isothermal cavity with a small opening.

The walls of the cavity are partially reflective and are kept at constant temperature, maintaining radiative equilibrium within the cavity. A hohlraum is also a perfect absorber since it traps all radiation that enters the small aperture.
