Fig. 9 — Graphical determination of mode shapes for a coupled resonator 

 reflex klystron having the secondary cavity Q equal to primary Q. (a) Load lines 

 for various degrees of coupling superimposed on small signal electronic admittance 

 spiral, (b) Power output versus repeller drift angle, (c) Frequency versus repeller 

 drift angle, (d) Power output versus frequency, (e) Power output, normalized 

 with resi)ect to its maximum value within the mode, shown as a function of fre- 

 quency.
