Fig. 20 — Quantitative verification of coupled resonator reflex klystron theory. 

 •Curves (a) and (b) were obtained experimentally by changing the repeller voltage 

 about its midmode value and noting the corresponding values of power and 

 frequency. Curves (c) and (d) were deduced from (a) and (b). The theoretical 

 curves were obtained graphically from a complex admittance plane plot similar 

 to those of Figs. 9 and 13.
