Title: Traveling wave tube
Inventor: WATANABE HIRONORI
IPC: H01J23/26
Filed: 1990-11-30
Abstract: PURPOSE:To enhance the efficiency by providing a helix with an equal pitch structure, and providing a support rod with a structure for gradually increasing the volume per unit length from the input side to the output side so as to synchronize the phase speed of electromagnetic waves propagated in the helix with the axial directional speed of electrons. CONSTITUTION:A helix 3 has an equal pitch structure, and a support rod 4 has the width gradually increased from input side to output side. Thus, the phase speed of electromagnetic waves can be minimized toward the output side, and the phase speed of the electromagnetic waves can be synchronized with the axial directional speed of electrons over the whole length of the helix 3. Since the electrons traveling in the helix 3 are more easily absorbed by the helix 3 as the speed is slower, the helix 3 has a high temperature on the output side, compared with the input side. However, since the width of the support rod 4 supporting the helix 3 is increased toward the output side, the contact area with the helix 3 is increased, and the helix 3 can be effectively prevented from having a higher temperature. Thus, the efficiency can be enhanced.
