The semi-empirical equation of Bohm (DB) doesn’t take into the account the fluctuation properties of plasma parameters in the plasma. So, the Bohm formula did not explain the diffusion behavior caused by instability. The 1/16 factor in Bohm formula represent the relation between the diffusion and the instability that causing it. Therefore, the Bohm factor studied as instability factor (C), this factor derived into two turbulence cases (strong and weak turbulence).The results of this factor was tested with experimental results in Q-machine and shown good results. The diffusion coefficients are drived according to this instability factor for strong and weak turbulence cases.
