Experiments on a laser-produced plasma cross-field motion for simulation of interaction between CRRES releases and geoplasma

Summary form only given. A new class of simulation experiments with laser-produced plasmas is discussed with reference to recent results of CRRES-mission investigations. For better understanding of a low-M/sub A/ interaction processes of ionospheric (VC36.06CE or G-9) and magnetospheric (G-10) barium releases with a surrounding magnetized geoplasma, simulation experiments are proposed at high-intensity magnetic fields. (Bo/spl ges/10-20 kGs) and with the presence of a low-density partially ionized background. Such experiments have become possible owing to successful simulations of the AMPTE-release and preliminary studies of cross-field plasma motion at B/sub 0//spl ges/10 kGs, performed at the "KI-1" facility in Novosibirsk, as well as due to extension of the possibilities of high-intensity magnetic field laser-produced plasma interaction experiments in Warsaw. In particular we hope to achieve the value of the main similarity criterion of the problem of the ion magnetization parameter. In such conditions, it is interesting to simulate the development of high-mode flute instabilities as well as propagation of plasma blobs across the field.
