Abstract:

The behavior of Brillouin beams in TWAs is evaluated. The effects of magnetic field strength, as well as other parameters, on the beam geometry and the r-f voltage buildup along the beam are presented. The radial distribution of electrons at the saturation plane is also determined for typical operating parameters. The continuation of work on the nonlinear, boundary-value problems in electron and plasma devices is described. A method of integrating the equations is presented and the error propagation in the solution is discussed. Experimental results obtained in the beam analyzer on a solid-beam gun are described. This gun is to be used eventually in the beam stability experiments in the presence of large-signal r-f. The magnetron injection gun computer program work is described. The cathode current density can now be reliably handled in the program, but cycloiding problems at the cathode are still shown to be present. The initial results from testing the UHF tube containing a magnetron injection gun are discussed. Future plans for this work are outlined. Operation under cw conditions is shown to be necessary in order to obtain noise measurements on the tube. Author
