Interaction of a fast magnetic field with non-magnetized plasma for the plasma opening switch case

We discuss the problem of the magnetic field penetration into a plasma and plasma acceleration by a magnetic field in the particular case of the Plasma Opening Switch. Resent experiments lead to the formulation of a new type of shocks, the Hall plasma shock-waves, and a basic description of such shock-waves is given. The discussion presented in this paper allows simple estimation of the POS conduction time and new estimation of the opening time.
