“…Therefore, the problem of plasma numerical heating caused by unresolved Debye length can be ignored. A high-voltage gas-discharge hydrogen plasma is considered [31,32], with ion mass m i = 1836m e and charge Z i = e, where m e is the electron mass. The plasma temperature and density are set to be T e = 4 eV and n e0 = 2.0 × 10 23 m −3 , respectively.…”

The study of the interaction between ion beam and plasma is very important to the areas of inertial fusion energy and high energy density physics (HEDP). With detailed one-dimensional (1D) electromagnetic particle-in-cell (PIC) simulations, we investigate here the interaction of a laser-accelerated proton beam assuming an ideal monoenergetic beam with a gas-discharge plasma. After the saturation stage of the two-stream instability excited by the proton beam, significant high energy electrons are observed, with maximum energy approaching 2 MeV, and a new two-stream instability occurs between the high energy electrons and background electrons. The trajectories of plasma electrons are studied, showing the process of electron trapping and de-trapping from the wakefield.

The L-shell X-ray emissions of iodine are investigated as a function of the incident energy for I22+ ions impacting on Fe target in the energy region near the Bohr velocity. Six distinct L-subshell X-rays, Lι, Lα1, 2, Lβ1, 3, 4, Lβ2, 15, Lγ1 and Lγ2, 3, 4, 4', are observed. Compared to the atomic data, the energy of the experimental X ray shifts to the higher energy side. The relative intensity ratios of Lι, Lβ1, 3, 4, Lβ2, 15, to Lα1, 2, Lι to Lβ2, 15 and Lγ2, 3, 4, 4/ to Lγ1 are enhanced, but has no obvious change with the increase of projectile energy in the present energy region. That is interpreted by the multiple ionization effect of the M-, N- and O-shell electrons.
