Application of additive technologies for the manufacture of a model of the slow system of a millimeter waveband traveling wave tube

Abstract

Using the technology of photopolymer three-dimensional printing with subsequent metallization, a prototype of a slow-wave system for a Q-band traveling wave lamp was manufactured. The deviations in the size of one period of the slow-wave system detected on the measuring microscope did not exceed 5 μm. The results of “cold” electrodynamic measurements of the manufactured system demonstrated good agreement with the calculated data.
