The properties of a cylindrical semiconductor plasma generated by injection and placed in a longitudinal magnetic field with a small transverse component are investigated both for the stable and unstable state. The plasma is described by the macroscopic equations of motion and continuity for electrons and holes. For the stationary case formulae are derived and discussed concerning the density distribution of the plasma as well as the radial and azimuthal electric field. The investigation of the density instabilities follows a method developed by Johnson and Jerde for parallel fields. It is shown that the introduction of a transverse component of the magnetic field leads to a coupling of the modes. In the simplest case this causes the simultaneous appearance of the n = 0 and n = 1 mode with the same frequency above certain threshold values of the fields. On this basis an explanation of the oscillistor effect is possible.
