| Abstract | ||
| The two modes of the ionization instability were sdudied; fast thermal mode and ionization mode. The diffusion of electrons by ionization instability was studied versus Hall angle using modified Bohm diffusion model .It was seen that the diffusion was very intensively at angles α = ±90 . The efficiency in current of the generator caused by the diffusion is studied at three different neutral atoms concentrations n= 1026 m-3 , n= 1027 m-3 and n= 1028 m-3 , it was seen that the efficiency in current increase up to 22% at Hall angle α =-90 and n=1028 m-3 . | ||
