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-Ma interaction processes of ionospheric and magnetospheric Barium releases with a surrounding magnetized geoplasma, simulation experiments are proposed at high-intensity magnetic fields 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 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, the authors hope to achieve the value of the main similarity criterion of the problem of the ion magnetization parameter, in common simulation experiments. In such conditions, it is very interesting to simulate the development of high-mode ({ge} 50) flute instabilities as well as propagation of plasma blobs across the field at the distance > Rh. In simulation of an ionospheric release, the main goal is to study the background plasma influence on such propagation, its acceleration by Ba cloud, and finally, recently revealed development of Langmuir and ion-cyclotron wave activities in the last processes. The authors present some discussion on the physics of the above mentioned interaction processes (for performing simulation experiments with adequate similarity criteria) as well as the parameters of such experiments and methods for their accomplishment.
