Title:
TRAVELLING WAVE TUBE MUTUAL OPERATION CIRCUIT WITH WIDE LADDER STAGE
Document Type and Number:
Japanese Patent JPS5828159
Kind Code:
A
Abstract:
A slow-wave circuit suitable for a high-frequency traveling-wave tube has an array of metallic ladder rungs extending transversely across an elongated envelope and not in contact with the envelope except at the ends of the rungs. The envelope has a cross-shaped section to provide a fundamental backward wave. The rungs preferably have aligned apertures to pass a beam of electrons in traveling-wave interaction with the circuit. By making the rungs transversely broader than a critical value, the lowest passband of the circuit has poles of impedance at both its ends, whereby more efficient interaction is obtained, along with greater stability.
