Measurements on the beam-plasma interaction occurring when an energetic ion beam is injected into a plasma are presented. Excitation of ion cyclotron harmonic waves propagating azimuthally across the applied magnetic field is observed. The excitation is attributed to the small velocity component of the ion beam directed perpendicular to the magnetic field, independent of the parallel velocity component. The experimental results are compared with the linear theory of electrostatic instabilities in a Maxwellian plasma traversed by a monoenergetic beam with d. c. energy components parallel and perpendicular to the magnetic field.

We present measurements proving the successive excitation of two distinct instabilities by electron beam–plasma interaction along a plasma column. The first, appearing near the gun, grows in space, until the beam is trapped in the wave electric field, and decays. In this process the time-averaged distribution function changes, from a δ-type distribution function, into a plateau. This new beam–plasma distribution is also unstable; and another instability grows until the beam is again trapped. Numerical calculations show that the second instability can be explained, assuming that the beam distribution thermalizes when propagating from the first instability to the second.
