Theoretical calculations and simulation data were presented to study the effect of the Xe-Dy mixture on properties of arc plasma. The effect of voltage, concentration and temperature on current flow density, power flux density and cathode temperature were studied. Different concentrations of Dysprosium (0.005, 0.01, 0.05, 0.1, and 0.5 mol) were used. The program (NCBL) was used in this work. Results showed a clear effect of concentration on plasma parameters, especially at the highest concentration, in addition to the effect of voltage. We notice that the current density increases from ≥3500k), while (3500 – 5000k) increases for all concentrations due to collisions as well as density of flowing energy For all the concentrations mentioned, we noticed that there is a clear effect of the temperature (≥ 3500k) on current density where increases and from (3500- 5000). we noticed an increase in the current density as well as the voltage especially at (25v) where the current and the energy overflow density increase due to elastic and inelastic collisions because acceleration of electrons with an increase in voltage.
