Non-neutral electron plasmas were confined in an axisymmetric magnetic mirror field of the mirror ratio R ∼ 3. Axial plasma oscillations (Trivelpiece-Gould modes), diocotron oscillations with the azimuthal mode number m = 2, and solitary waves were investigated experimentally. It was observed that the velocities of an electron soliton and an electron hole decreased at high field side in a magnetic mirror confinement.
