Electron beam plasma interaction Collimation of fast electron beams by modifying the background plasma density.
Dusty (Complex) plasmas • Electron Emission Thermionic, photoelectric and secondary electron emission from spherical and cylindrical particles;
Quantum effects: plane, spherical and cylindrical surfaces & expression for transmission coefficient valid for any arbitrary electron energy;
Theoretical prediction of thermionic/ photoelectric enhancement of emission current. • Electron Accretion Quantum effects: Collection of electrons over particles through tunnelling. • Formulation of kinetics for complex plasmas Approach incorporates the openness nature of the plasma and energy balance of all the plasma constituents along with inherent electronic mechanisms of ionization/ recombination. • Charging kinetics of complex plasmas Uniform potential theory for dust particles characterized by a size distribution function;
Mie scattering contribution to the charging kinetics & a theoretical basis for explanation of opposite charging of smaller and larger particles simultaneously;
Different material dust • Applications Near space, Comets, Saturn rings, WIM, ISM, NLC & PMSE structures • Lattice wave Effect of attractive potential between charged grains on dispersion relations Laser plasma interaction Prediction of the condition & region for bright ring formation in self focusing region Development of a paraxial like approach, applicable to the central hollow beams (e.g. DHGBs)
