“…The discussion in the previous section remains silent on one important feature of the instability with finite k z : namely on the regime of the Modified-Two-Stream Instability (MTSI) 22,30,31 where the effect of the electron parallel motion is typically considered in the context of the following dispersion equation 30…”

The Electron Cyclotron Drift Instability (ECDI) driven by the electron E × B drift in partially magnetized plasmas is investigated with highly resolved particle-in-cell simulations. The emphasis is on two-dimensional effects involving the parallel dynamics along the magnetic field in a finite length plasma with dielectric walls. It is found that the instability develops as a sequence of growing cyclotron harmonics demonstrating wave breaking and complex nonlinear interactions, being particularly pronounced in ion density fluctuations at short wavelengths. At the same time, nonlinear evolution of fluctuations of the ion and electron density, as well as the anomalous electron current, shows cascade toward long wavelengths. Tendency to generate long wavelength components is most clearly observed in the spectra of the electron density and the anomalous current fluctuations. An intense but slowly growing mode with a distinct eigen-mode structure along the magnetic field develops at a later nonlinear stage enhancing the tendency toward long wavelength condensation. The latter mode having a finite wavelength along the magnetic field is identified as the Modified Two-Stream Instability (MTSI). It is shown that the MTSI mode results in strong parallel heating of electrons.

The crystallization process of fluoride glass HBANI after combined deformation (compressive and torsional strain) of ε = 4 and annealing to crystallization temperatures was studied by differential scanning calorimetry and X-ray diffraction.The glass transition temperature and the crystallization temperature, the sequence of the crystalline phases emerging was determined. It is shown that the crystallization rate of fluoride glass decreases after combined deformation.

The crystallization kinetics of Co based amorphous alloys after severe plastic deformation was studied by differential scanning calorimetry, X-ray diffraction and scanning probe microscopy. Severe plastic deformation was achieved by barocryodeformation (all-round compression). The results are compared with biaxial stretching by ion irradiation. It is shown that the crystallization rate increases after biaxial stretching and decreases after all-round compression.
