A theoretical analysis of the scaling law and the value of the threshold current for beam plasma discharge is presented, based on the requirement for an absolute instability near the plasma frequency. It is shown that both the scaling law as well as the numerical values of I sub C are consistent with the experimental data, both in the low and high pressure regimes for weak magnetic field experiments small omega sub e capital omega sub e. The differences in scaling between the regimes are attributed to transition from bohm to classical diffusion. It is found that the value of the pressure minimum for ignition increases linearly with the ambient magnetic field. Author
