Necessary conditions are formulated for the generation of a double layer at the interface of a complex plasma and a particle-free electron-ion plasma in a weakly collisional discharge. Examples are calculated for realistic observed complex plasmas, and it is shown that situations of both “smooth” transitions and “sharp” transitions can exist. The model can explain the abrupt boundaries observed.

    The kinetics of nanoparticle coagulation has been studied in fractionally charged and charge fluctuating dusty plasmas. The coagulation occurs when the mutual collision frequency among nanoparticles exceeds their charging and decharging/neutralization frequency. Interestingly, the coagulation is...

    Bissell and Johnson [Phys. Fluids 30, 779 (1987)] have calculated the electrostatic potential variation in the sheath and presheath regions of a collisionless plasma in which the source of ions is assumed to be Maxwellian. To do this, they imposed the generalized Bohm criterion as a boundary...

    The expansion of pure electron plasmas due to collisions with background neutral gas atoms in the Electron Diffusion Gauge experiment device is observed. Measurements of plasma expansion with the new, phosphor-screen density diagnostic suggest that the expansion rates measured previously were...

    The effect of discrete plasma transport by coherent structures on plasma-wall interactions in the scrape-off-layer (SOL) is illustrated by a simple model problem. A one-dimensional ballistic model is studied in which a periodic train of plasma blobs creates a series of discrete pulses of neutral...

    Emitted electrons are accelerated back into the plasma by the sheath. If their mean free path is large, they can propagate directly to another surface without suffering collisions. We analyze the effects of 'transit' on plasma-surface interaction. When transit occurs, surfaces exchanging...

    A new negative ion extraction geometry with streaming neutral gas injector (SNGI) was tested in its performance to enhance negative hydrogen ion (H-) at low operational pressure. The experiments were performed using a test ion source equipped with a SNGI having the wall perpendicular to the gas...

    The free energy associated with shear in the equilibrium parallel electron velocity is shown to be responsible for the excitation of low-frequency electromagnetic waves in collisionless magnetoplasma. New dispersion relations are derived by using the hydrodynamic equations for the electron...
