Zusammenfassung:This paper presents some experimental results of unloaded Q-factor, Q 0 , measurements in klystron cavities using the critical points method. The circuit model and impedance locus involving this method are outlined in order to present the experimental procedure. The values calculated for a typical reentrant S-band klystrons cavity, using a vector network analyzer, were 3394 for the unloaded Q 0 , 1.2715 for the coupling coefficient and 2.85818GHz for the load resonant frequency.
