Nearly 10 years of Nova [E. M. Campbell, Laser Part. Beams {bold 9}, 209 (1991)] experiments and analysis have lead to a relatively detailed quantitative and qualitative understanding of radiation drive in laser-heated hohlraums. Our most successful quantitative modeling tool is two-dimensional (2-D) LASNEX numerical simulations [G. B. Zimmerman and W. L. Kruer, Comments Plasma Phys. Controlled Fusion {bold 2}, 51 (1975)]. Analysis of the simulations provides us with insight into the physics of hohlraum drive. In particular we find hohlraum radiation conversion efficiency becomes quite high with longer pulses as the accumulated, high-{ital Z} blow-off plasma begins to radiate. Extensive Nova experiments corroborate our quantitative and qualitative understanding. {copyright} {ital 1996 American Institute of Physics.}
