Abstract: 

IN THIS WORK, USING A TWO- FLUID MODEL, THE STRUCTURE OF SHEATH IN ACTIVE MAGNETIZED PLASMAS IS INVESTIGATED FOR DIFFERENT VALUES OF ION TEMPERATURE. IN ORDER TO DO THIS, CONSIDERING THE EFFECTS OF IONIZATION, ION-NEUTRAL AND ELECTRON-NEUTRAL COLLISIONS, THE BASIC EQUATIONS OF THE MODEL (THE MOMENTUM AND CONTINUITY EQUATIONS FOR ELECTRONS AND IONS) WILL BE SOLVED NUMERICALLY AND THE EFFECT OF ION TEMPERATURE ON PLASMA SHEATH STRUCTURE SUCH AS SHEATH THICKNESS, NET CHARGE DENSITY IN THE SHEATH AND ION IMPACT ENERGY ON THE CATHODE WILL BE ANALYZED.
