| Abstract | ||
| The modified Bohm diffusion equation is studied in the inner region of plasma column in Q-machine. The instability factor (C-factor) and modified Bohm diffusion efficient are calculated in that region of plasma column. The results are compared with those calculated according to Bohm equation and with experimental results. The comparison with experimental shows a better agreement when the instability factor (c) is taken into the account. The diffusion coefficient and the instability factor are calculated for strong and weak turbulence case. The results of both cases are examined with Bohm diffusion equation as well as with experimental results. A good fitting has been obtained for strong turbulence results with experimental results. Whereas, an approximate agreement are found between weak turbulence results in the region near from a center and edge of plasma. | ||
