Abstract
A supporting system for a delay line of a travelling wave tube wherein a number of clamping rings press dielectric support rods against the delay line. The clamping rings have a natural length along the delay line and a spacing distance such that (N.multidot.w.lambda.)/4=L.sub.1,2, where L.sub.1,2 designates the length of the line resonators, .lambda..sub.w the wave length on the delay line, and N a whole uneven number.
Claims3
A supporting system for a helical or ring-bar delay line of a travelling wave tube, comprising:
- a delay line held by a plurality of dielectric support rods arranged parallel to one another along generating lines of the delay line;
- a plurality of clamping rings of resilient material being shaped and positioned to press the support rods against the delay line;
- and the clamping rings having a natural length L.sub.1 in a direction along the delay line and a distance L.sub.2 from one another such that ##EQU2## where L.sub.1,2 designates the length of resonance sections or line resonators of the line, .lambda..sub.w the wave length on the delay line, and N a whole uneven number (1,3 . . . N).
