Notes:
In order for inertial confinement fusion (ICF) capsules to achieve high gain, they must not break up because of hydrodynamic instability, the fuel should be maintained on a low adiabat, and the peak laser intensities should be below thresholds of various plasma instabilities. In this paper the results of two-dimensional computer calculations modeling the growth of hydrodynamic instabilities of slabs directly driven with a laser are reported. In order for direct drive capsules to succeed with capsule finishes of 100–300 A(ring), the capsules must be imploded on an adiabat a factor of 3– 4 in pressure above a Fermi-degenerate adiabat or techniques must be developed for producing density gradient scale lengths of about half the shell thickness. These conclusions depend only weakly on the laser intensity.
