Collective Ion Acceleration.
Abstract
Work was conducted on the excitation of slow cyclotron and slow space charge waves in a plasma beam. Observations were made when a planar electron beam was propagated through a strip line. The beam was guided by a homogeneous magnetic field and the excitation achieved with a zero frequency pump wave. Both the space charge and cyclotron waves were excited in the 20-30 GHz interaction and the cyclotron wave in the 70 GHz range. For the first time, independent measurements were made of the effects on growth rate of the homogeneous guide field and the rippled field. Experiments were conducted on the proof-of-principle for a space charge wave accelerator. A large amplitude space charge wave was grown on an electron beam. Phase velocities of 0.25 c, and accelerating fields of 60kV/cm were obtained. (Author)
