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.
