METHOD DETERMINING PARAMETERS OF SLOW-WAVE STRUCTURES

摘要

FIELD: measurement technology. SUBSTANCE: method involves excitation of slow- wave structure placed in cylindrical cavity resonator which ends are left open in specified frequency range, measurement and recording of all resonance frequencies fom1 and Q-factors Qom1 on these frequencies in specified range. Then length of slow- wave system is shortened by value of and all resonance frequencies fom2 in this frequency range are measured again. Moderation factors nm on resonance frequencies and electrodynamic parameters of slow-down structure are determined by computation by given formulas and dispersion dependencies a=a(f) are plotted, where a is any electrodynamic parameter while measured resonance frequencies fom are taken as argument f. EFFECT: provision for measurement of resonance frequencies by method of electrodynamic parameters needed for design of slow-wave structures. 5 dwg, 4 tbl
