Book excerpt: 27The two-dimensional analysis for large signal phenomena in traveling-wave devices and klystrons has been employed to obtain solutions to drift-space interaction phenomena. The velocity components and harmonic current components within an electron stream are presented. The nonlinear theory for the solution of large-signal phenomena in microwave devices by a density function method has been checked. The Langmuir diode has been used as a test case. The agreement with the known results for this geometry is excellent. The work on a tube using a helix-type slow-wave circuit with two successive step changes in the phase velocity near the output end of the tube is described. The initial results are summarized. Cold test data on the ring-and-bar tube in the presence of a conducting shield around the slow-wave circuit has been obtained. These results are presented in detail in the form of a series of curves.
