“…Malamud et al studied the evolution of RTI in the design of a laser-driven experiment and examined the reacceleration phenomenon [34]. Sauppe et al designed a cylindrical implosion experiment using the radiation-hydrodynamics code xRAGE for the OMEGA and NIF laser facilities [35]. Wu et al concentrated on nonlinear dynamics and analyzed the 3D single-mode RTI at a higher Atwood number [36].…”

The presence of plasma density gradient is one of the main sources of Rayleigh–Taylor instability (RTI). The Rayleigh–Taylor instability has application in meteorology to explain cloud formations and in astrophysics to explain finger formation. It has wide applications in the inertial confinement fusion to determine the yield of the reaction. The aim of the chapter is to discuss the current status of the research related to RTI. The current research related to RTI has been reviewed, and general dispersion relation has been derived under the thermal motion of electron. The perturbed densities of ions and electrons are determined using two fluid approach under the small amplitude of oscillations. The dispersion equation is derived with the help of Poisson’s equation and solved numerically to investigate the effect of various parameters on the growth rate and real frequency. It has been shown that the real frequency increases with plasma density gradient, electron temperature and the wavenumber, but magnetic field has opposite effect on it. On the other hand, the growth rate of instability increases with magnetic field and density gradient, but it decreases with electron temperature and wave number.

“…Nearly all of the studies on the targets for heavy ion fusion are of spherical geometry. The present investigation focused on the cylindrical implosions driven by a single ion beam incident with high symmetry relative to the target axis [52][53][54][55][56]. There are several advantages of cylindrical targets.…”

A magnetized cylindrical target composed by a gold tube filled with deuterium-tritium fuel plasma at low density is studied numerically in the present paper. A shock wave is produced when a heavy ion beam heats the gold along the direction of the magnetic field. The density peak of the shock wave increases with the increase of the time and it propagates in the −r direction in the cylindrical tube. It seems that this wave is the supermagnetosonic wave. It is found that the Mach number M is between 6.96 and 19.19. The density peak of the shock wave increases as the intense of the heavy ion beam increases. Furthermore, the density peak of the shock wave increases as the external magnetic field increases.
