The purpose of the work is to investigate the interaction of electromagnetic waves and charge carriers in vacuum and solids. The construction of a crossed-field amplifier which will incorporate the results of our noise studies is in progress. Work on the crossed-field gun design method developed by R. A. Rao is being carried on to obtain designs for magnetically shielded guns. A method was developed for magnetically shielded guns. A method was developed for the application of a variational technique to reach an optimum compromise between desirable forms of variation of potential and beam thickness along the beam. An experimental and theoretical evaluation of the crossed-field acoustic-wave amplifier is being conducted. The comparison of optimum performance of ZnO longitudinal acoustic amplifiers with the InSb crossed-field counterparts has continued with an effort being made to get an improved basis for comparison in heat dissipation capabilities. The solution of the heat-flow problem is required before definite conclusions can be reached from the calculations. Author
