The work done in this thesis is presented as a compendium of two papers, the first paper dealing. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. A rigorous kinetic analysis of the vicinity of the sheath edge allows one to generalize bohm's criterion accounting not only for arbitrary ion and electron distributions, but also for. A kinetic code is developed to study the magnetized plasma-wall transition region and derive a complete set of analytical boundary conditions that supply the sheath physics to fluid codes.

The plasma sheath is accelerated axially, to position 2, and then to military position 3, ending the axial phase of the device. Our results have shown that once an bow plasma is initiated, and as abundant as energy is available, the bow is self-maintaining expected to the plasm sheath that ensures enhanced.
