Abstract:

The program to determine a slow-wave interaction structure for high-power traveling-wave tubes resulted in the development of a circuit termed the ring-loaded meander line. This circuit, demonstrating freedom from interfering modes, high interaction impedance, 70 bandwidth, and better than 1-megawatt power-handling capability at S band, can lead to an entire array of traveling-wave tubes. A theoretical analysis of the ring-loaded transmission line, a generic ancestor of the meander line, was performed to seek solutions to the determinantal equation fk, beta 0. By introducing a meander factor, the results were applied to the meander line circuits. Extensive cold testing was performed by varying the geometric parameters and observing the effects upon dispersion, impedance, and frequency characteristics. A hot-test structure, a tube to demonstrate the meander line at peak power and full bandwidth, was designed and partially assembled. Author
