Abstract:

The ionization occurring during the initial phase of an axisymmetric electrodeless discharge has been investigated. In the axisymmetric electrodeless discharge considered, the electric field and the currents are in the azimuthal direction, while the magnetic field is axial. If the capacitor bank is switched on in a time small compared with the period of the discharge, the electric field rises to its full value in a time during which the magnetic field is still very small. Then, a model is appropri te in which at the time zero the electric field is instantly present at its full value, while the magnetic field is zero. Therefore, there must exist a time interval for which the magnetic field can e neglected. This time interval is called th initial phase it ends at time, t, which is defined as the time for which the magnetic force on an electron is 110 of the electric force. Since it is shown that during t the plasma does not move much in the radial direction, t is called the mass motion time. The analytical investigation has been restricted to the initial phase the magnetic field has been neglected, but the electric field induced by the change of magnetic field is accounted for. Author
