Abstract: The optical regularities of the development of the plasma channel of a high-pressure pulse discharge are investigated in the presence of high gradients of magnetic field at the plasma–neutral gas interface ($\nabla P_H\sim10^9$ Pa/m) and a low inductance per unit length of the discharge circuit ($L\sim10^{-4}$ H/m). It is shown that, when the rate of delivery of electric energy into the discharge gap varies and in the presence of intensity of external magnetic field, the dynamics of zones of high conductivity and brightness of glow change significantly. The behavior of the temporal evolution of the distribution of the radiation intensity over the spectrum in the optical range is studied.
