METHOD DETERMINING PARAMETERS OF SLOW-WAVE STRUCTURES Russian patent published in 1999 - IPC

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 f_om1 and Q-factors Q_om1 on these frequencies in specified range. Then length of slow- wave system is shortened by value of Δl_sp≤ 0,1l_sp and all resonance frequencies f_om2 in this frequency range are measured again. Moderation factors n_m 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 f_om 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
