Abstract

In experiments, the momentum and angular momentum of the slow magnetosonic and torsional Alfven waves produced by irradiating train of laser pulses of the target in a magnetic field in a vacuum or in a rarefied plasma with a magnetic field were investigated. At "resonance" of plasma bunches with background, a single Alfven wave and a single slow magnetosonic wave are formed. These waves transfer a momentum in a narrow tube of the magnetic field, angular momentum variation of the current, and the electric field. [ABSTRACT FROM AUTHOR]

Abstract

The fast non-MHD development of large-scale flutes at the boundary of plasma clouds expanding into magnetic field is a very common but still unclear phenomenon in a lot of geophysical (AMPTE Barium releases) and laboratory (laser plasma) experiments. To study its specific physics under conditions of the finite value of ion Larmor radius we had compared the data of AMPTE simulation at KI-1 facility with computer runs by electron Hall/MHD and Hybrid codes with taking into account magnetic field's diffusion relevant to the effect of anomalous electron collision frequency. It was found that the main experimentally observed features of flutes (their increment and non-linear stage) could be correctly described by these models. However, it requires this collision frequency of electrons to be proportional to their gyrofrequency, with values close to estimates derived earlier from KI-1 experiments through the phenomenology analysis of diamagnetic properties of exploding plasmas.
