Summary
Ion acceleration has been obtained experimentally in the beat wave configuration, wave acceleration demonstrated in the converging guide geometry, and strong electric fields have been obtained and measured in the waves. The simulation effort in the Cornell theory program has proceeded to the point where satisfactory wave propagation has been throughout the converging guide, non linear wave propagation effects have been detected and studied, and a design of a converging guide assembly completed with acceleration of test ions. Numerical values of the wave phase velocities obtained match, or are lower than those found experimentally under comparable conditions. The simulation electric fields agree to within a factor of two with those measured experimentally. We have also identified a variety of new problems which require further study. These include the observation of fast waves in the beam and also, in the long pulse (approx. 0.5 ..mu..sec) system, the onset of backward wave oscillations. The reflection of waves from the end of the wave growth structure has been observed recently by the MRC group who are working on design approaches to minimizing this effect. We review the different aspects of the Cornell theory and experiment program.
