Popis:	A rolling‐ball analogue for the motion of electrons in a high‐frequency longitudinal field has been developed in which the balls, injected at regular time intervals, plotted photographically a family of graphs of distance against time, indicated the electron bunching, velocity modulation, and density modulation. From these graphs the current densities were found as a function of time for a series of equally spaced positions between cathode and anode, and the plate current induced by the electron stream was computed. Graphs of conductance against transit angle revealed that the conductance was independent of the size of signal for indices of modulation 0.25, 0.50, and 0.75. When the transit angle was 2π the induced plate current was almost pure first harmonic plus dc. When the transit angle was 3π the first harmonic disappeared.
