Abstract

Our basic-plasma experiments relating to fusion-oriented and space plasmas have yielded deep and unique insight into wave and instability physics in ordinary electron-ion and unusual pair-particle plasmas. Here recent results on flow shears, polarization reversal and pair-ions are presented in the way that light is shed on the underlying physics.
