If the plate is then set upon the wax, a small fraction of the conduction electrons
from the plate will flow to the points of contact with the wax, but there are actually
very few points of contact and the major effect is the separation of charge on the ...

In ordinary operation the screen is kept at a fixed positive potential of the order of
that of the plate Eb. This rather large positive potential is necessary since the
cathode as well as the control grid is screened from the plate, and it is the screen
