Vv. Bychkov et al., SELF-CONSISTENT MODEL OF THE RAYLEIGH-TAYLOR INSTABILITY IN ABLATIVELY ACCELERATED LASER-PLASMA, Physics of plasmas, 1(9), 1994, pp. 2976-2986
A self-consistent approach to the problem of the growth rate of the Ra
yleigh-Taylor instability in laser accelerated targets is developed. T
he analytical solution of the problem is obtained by solving the compl
ete system of the hydrodynamical equations which include both thermal
conductivity and energy release due to absorption of the laser light.
The developed theory provides a rigorous justification for the supplem
entary boundary condition in the limiting case of the discontinuity mo
del. An analysis of the suppression of the Rayleigh-Taylor instability
by the ablation flow is done and it is found that there is a good agr
eement between the obtained solution and the approximate formula sigma
= 0. 9 square-root gk - 3u1k, where g is the acceleration, u1 is the
ablation velocity. This paper discusses different regimes of the ablat
ive stabilization and compares them with previous analytical and numer
ical works.
