A linear perturbation computation method applied to hydrodynamic instability growth predictions in ICF targets

A linear perturbation computation method is used to compute hydrodynamic instability growth in model implosions of inertial confinement fusion direct-drive and indirect-drive designed targets. Accurate descriptions of linear perturbation evolutions for Legendre mode numbers up to several hundreds have thus been obtained in a systematic way, motivating further improvements of the physical modeling currently handled by the method.
