We then investigate this by particle simulations. The maximum speeds of the heavy species are about the same, of the order of the wave propagation speed. These are in good agreement with theoretical prediction. These results indicate that, if high-energy ions are produced in the solar corona through these mechanisms, the elemental compositions of these heavy ions can be similar to that of the background plasma, i.e., the corona. This paper presents a comparison between experimental results and recently developed nonlinear theory.
Many features observed in experiment are compatible with the consequences of the nonlinear theory.
Examples include the structure of the saturated pulse that emerges from the onset of instability of a single mode, and the decrease, but persistence of, TAE signals when the applied rf power is reduced or shut off. We consider the interaction of subpicosecond relativistically strong short laser pulses with an underdense cold unmagnetized electron plasma. Since the electron density distribution is determined completely by the pump wave intensity, the generated magnetic field is negligibly small for nonrelativistic laser pulses but increases rapidly in the ultrarelativistic case. In extremely dense plasmas, highly intense laser pulses in the self-channeling regime can generate magnetic fields approximately 100 MG and greater. The turbulence driven by the ion temperature gradient, the mass shear-flow parallel to the magnetic field, and the impurity ion density gradient in confined plasmas is studied in a sheared slab magnetic configuration.
