“…[1][2][3] It is well known that when a test charge passes through an electron-ion plasma, it loses energy via the wave-particle interaction or simply by the interparticle collisions. 7 Recently, Bringa and Arista 8 studied the collective and individual contributions to the energy loss of correlated ions for typical parameters of the ICF, Z-pinch, and tokamak plasmas. 4 and 5.…”

“…The transport of cluster ions in plasmas has been usually studied as a correlated electronic stopping [7][8][9][10][11] and not much attention has been devoted to investigating a complete process where all main cluster interactions are taken into account. This complete process has been studied regularly in solid targets during the past [12][13][14][15][16], but it is not until now that these studies extend to plasma targets.…”

The objective of the present work is to study the target electronic and nuclear interactions produced when a H + 2 ion traverses classical plasma matter. Electronic interactions are treated by means of the dielectric formalism while nuclear interactions are dealt within the classical dispersion theory through a Monte Carlo computer code. The interactions through plasma electronic medium among close ions are called wake forces. We checked that these forces screen the Coulomb explosions of the two fragmented protons from the same H + 2 ion decreasing their relative distance in the analysed cases. These forces align the interproton vector along the motion direction. They also tend the two-proton energy loss to the value of two isolated protons when at early times it is rather larger. Nevertheless most parts of these wake effects cannot be corroborated experimentally as they are masked by the projectile collisions with target nuclei in our numerical experiment. These collisions cancel the screening produced by the wake forces, increasing the interproton distance even faster than for bare Coulomb explosion. Also they misalign the interproton vector along the motion direction and contribute moderately to increase the energy loss of the fragmented H + 2 ion. These nuclear collisions effects are more significant in reducing projectile velocity.

“…Such effects arise due to the collective response of the plasma to the incoming projectiles. Later, the energy loss of fast ions was calculated in an electron plasma under the influence of plasma wakes produced by incoming charged projectiles for collinear and non-collinear cases [11]. The collective and individual contributions to the energy loss of correlated ions were also investigated by taking some typical parameters of ICF, Z-pinch and tokamak plasmas [12].…”

Effect of Charge Fluctuations on the Debye Shielding and Energy Loss ofN×MProjectiles in a Dusty Plasma

et al. 2003

The electrostatic potential and the energy loss by N × M projectiles propagating through a dusty plasma are derived within the frame work of dielectric theory for different dust parameters of interest. An interference contribution of these projectiles to the potential and energy loss is observed which depends upon the separation between them and their orientation. The dynamic dust charge produces a potential well instead of a coulombic type potential for a slowly moving test charge having small charge relaxation rate and energy is gained by the charged projectiles. However, fast charge relaxation enhances the energy loss and some peaks are also observed showing the excitation of some electrostatic modes. These results are useful to explain the coagulation of dust grains in laboratory and space plasma as well as in the field ion-beam driven ICF scheme.
