Prompt losses of ions having turning points in the vicinity of the poloidal field null of a snowflake divertor are analyzed. Classification of the ion trajectories is presented. It is concluded that prompt losses in a snowflake affect a broader zone than in the standard X-point divertor. The size of the phase-space “hole” produced by prompt losses is evaluated.

    A numerical study, employing the particle code RINGA [Plasma Phys. 23, 521 (1981)], of two ion rings that merge with each other due to their mutual magnetic attraction is presented. It is shown that an ion ring with closed magnetic field lines (field reversed) can be formed by merging two weaker...

    The plasma equation for a warm collisionless plasma with a Maxwellian particle source is solved in plane parallel geometry. The generalized Bohm criterion is used to identify the plasma-sheath boundary. This kinetic treatment, in common with fluid and cold-ion kinetic models, results in an...

    An experimental study of the formation of voids (dust-free regions) around negatively biased probes in a dusty plasma is described. Stable voids are maintained by the balance of electric and ion drag forces on the dust particles. A theoretical model is proposed to explain how the size of the...

    Dielectronic recombination (DR) is an important atomic physics process that is relevant to astrophysical plasma modeling. DR is responsible for the charge state balance as well as the cooling of plasmas, and it is the dominant electron-ion recombination process for most ions in both photoionized...

    A one-dimensional electromagnetic particle-in-cell (PIC) model is used to investigate the Alfvén ion-cyclotron (AIC) instability in high-β plasmas with large ion temperature anisotropies. The simulation results are compared with linear and quasilinear theory. Nonlinear effects, such as the...

    Ion acoustic solitary waves in three-component plasmas with nonisothermal electrons, positrons and ions are studied. The Sagdeev pseudo-potential method has been used in this work. The trapping parameter ( β), the ratio of the free electron temperature to the trapped electron temperature, is...
