Fig. 23.— Configurations of electric fields, magnetic fields, and anode potentials for the 

 n = 0, 1, 2, 3, and 4 modes of a resonator system having eight resonators. For each field 

 pattern of periodicity n, the configuration of the electric lines of force in the magnetron 

 interaction space is shown at the left, the configuration of the magnetic lines threading the 

 resonators is shown at the upper right, and anode potential waves are shown at the lower
