Sheath characteristics in collisional magnetized plasma with nonextensive electrons and thermal ions

Sheath formation and its characteristics are studied in collisional magnetized plasma consisting of nonextensive electrons thermal ions. Using two-fluid model, the Bohm criterion for ion velocity is deduced as a function parameters shown that ion-neutral collisions impose an upper limit criterion. It also found deviation from standard Maxwellian distribution significantly affects sheath characteristics. potential density considered under effects magnetic field, temperature, nonextensivity collision frequency. The results indicate by applying external it possible to control thickness.
