“…Let us analyze expression (8) in the case when a particle moves in a plasma with a sufficiently strong magnetic field. Let us assume the magnetic field, on one hand, reasonably weak and not to be quantized (hω c < k B T or a c ≫ λ B ), and, on the other hand, comparatively strong so that the cyclotron frequency of the plasma electrons exceeds the plasma frequency ω p = 4πn 0 e 2 /m or a c ≪ λ D , where a c is the Larmor radius and λ D is the Debye length λ D = v T /ω p .…”

“…Energy loss of fast charged particles in a plasma has been a topic of great interest since the 1950s [1][2][3][4][5][6][7][8] due to its considerable importance for the study of basic interactions of the charged particles in real media; moreover, recently it has also become a great concern in connection with heavy-ion driven inertial fusion research [5][6][7][8].…”

The analytical and numerical investigations of the energy loss rate of the test particle in a magnetized electron plasma are developed on the basis of the Vlasov-Poisson equations, and the main results are presented. The Larmor rotation of a test particle in a magnetic field is taken into account. The analysis is based on the assumption that the energy variation of the test particle is much less than its kinetic energy. The obtained general expression for stopping power is analyzed for three cases: (i) the particle moves through a collisionless plasma in a strong homogeneous magnetic field; (ii) the fast particle moves through a magnetized collisionless plasma along the magnetic field; and (iii) the particle moves through a magnetized collisional plasma across a magnetic field. Calculations are carried out for the arbitrary test particle velocities in the first case, and for fast particles in the second and third cases. It is shown that the rate at which a fast test particle loses energy while moving across a magnetic field may be much higher than the loss in the case of motion through plasma without magnetic field.

“…Beamplasma interaction experiments have revealed the enhancement of the stopping power due to plasma effects~Young et al, 1982;Hoffmann et al, 1990;Couillaud et al, 1994;Jacoby et al, 1995!. Most of the experiments used discharge plasma targets because they were superior in uniformity, line density, and lifetime to the other plasma targets such as laser-produced plasmas. However, the strong magnetic field induced by large discharge current often prevented the beams from penetrating the target effectively, which resulted in unwanted beam signal attenuation~plasma-lens effect!.…”

Stopping power of dense helium plasma for fast heavy ions

et al. 2003

The interaction process between fast heavy ions and dense plasma was experimentally investigated. We injected 4.3-MeV0u or 6.0-MeV0u iron ions into a z-pinch-discharge helium plasma and measured the energy loss of the ions by the time of flight method. The energy loss of 4.3-MeV0u ions fairly agreed with theoretical prediction when the electron density of the target was on the order of 10 18 cm Ϫ3 . With increasing electron density beyond 10 19 cm Ϫ3 , the difference between the experiment and the theory became remarkable; the experimental energy loss was 15% larger than the theoretical value at the peak density. For 6.0-MeV0u ions, the deviation from the theory appeared even at densities below 10 19 cm Ϫ3 . These discrepancies indicated that density effects such as ladderlike ionization caused the enhancement of the projectile mean charge in the target.
