Currently, these fusion fuel targets are placed inside a hollow spherical hohlraum chamber (from the German word <<hohlraum>>-<<cavity>>) with holes through which laser beams fall into it.

In this equation, temperature caused by fluid pressure loss is calculated by the equation [T.sub.fa] = (1/[[rho].sub.m][C.sub.m])(d[P.sub.fa]/dz); A = [??][C.sub.pm]([K.sub.f] + [R.sub.w] [U.sub.a][T.sub.D])/2[pi][R.sub.w][U.sub.a][K.sub.f], [T.sub.ei] is well wall temperature, [degrees]C; [K.sub.f] is formation layer thermal conductivity, J/([m.sup.2] x s x [degrees]C); [R.sub.w] is well radius, m; [U.sub.a] is heat transfer coefficient between hohlraum drill fluid and well wall in the well string, J/([m.sup.2] x s x K).
In an inertial confinement reactor, about 200 laser beams are focused in the target chamber, which is also called a hohlraum, on a single point.

Detailed May 18 in Nature Photonics, the design relies on a hohlraum, a small metal cylinder that holds hydrogen fuel in laser fusion experiments (SN: 4/20/13, p.
The next stage of the experiment involves a tiny gold can called a hohlraum (German for 'empty room').

In den Hohlraum zwischen des fernen Gott und der von ihm bis auf den Seidenfaden der Schopfung gelosten Welt stromen die Engel und Damonen ein.
With x-ray drive, the capsule is mounted in the center of a cylindrical high-Z (e.g., gold) can called a hohlraum. The laser beams illuminate the wall of the can (instead of the capsule surface) filling it with a uniform x-ray radiation field.
