The effect of the mechanical tolerances of a dielectric rod on the normalized phase velocity and interaction impedance of the helix slow‐wave structure used in traveling‐wave tubes is analyzed. In this letter, one of the most common rod shapes, the T‐shaped rod is considered, highlighting how the three geometrical dimensions, typical of this rod, affect the above‐mentioned helix slow‐wave characteristics. © 2000 John Wiley & Sons, Inc.
