Abstract
Plasma generator which is constructed and operated to provide an enhanced probability of collisions between charged and neutral particles in the working chamber together with enhanced energy transfer and uniformity of the plasma. The plasma generator includes a chamber (1) with means to produce electrons (5) and to cause the electrons to rotate and spiral (6,7) to produce ion of gases introduced into the chamber to produce a plasma. The plasma is contained by magnetic mirrors (10,11) at each end of the chamber (2). Axial oscillation of the plasma is produced by a low frequency oscillating potential (9) in the chamber to significantly increased ion electron interaction.
