Abstract : A new type of beam plasma interaction is described in which the basic rf motion is transverse to the dc velocity of the beam. It is shown that instabilities should occur near the electron plasma frequency. In the presence of a magnetic field further instabilities occur near the ion plasma frequency. An experiment has been performed to check the theory using an ion focused beam without magnetic field. As much as 25 db gain was observed in a 10 cm length at 450 Mc/s. (Author)
