The implosion of an inertial-confinement-fusion (ICF) capsule is most efficient if the imploding flow is exactly spherically symmetric. It is well known, however that real ICF flows are subject to a variety of fluid instabilities that destroy spherical symmetry. An experiment has been devised in cylindrical geometry that allows for the study of instability growth during an implosion. Results from these experiments have shown the effects of {open_quote}{open_quote}feedthrough{close_quote}{close_quote} of the instability from the ablation front, the effects of convergence, and the transition from linear to nonlinear growth regimes. The design of the cylinders and the drive configuration will be discussed, after which results are presented. Growth factors greater than ten have been created with these experiments. {copyright} {ital 1996 American Institute of Physics.}
