Deflection e/m Tube

Description

Highly evacuated electron tube with focusing electron gun and
fluorescent screen inclined relative to the beam axis, so that
the path of the beam can be seen and the effects of electric
and magnetic fields can be studied. The electron beam can
be deflected electrically in the electric field of the built-in plate
capacitor, and magnetically by using the Helmholtz coil pair.
By adjusting the electric field so that it cancels the magnetic
deflection, it is possible to determine the specific charge e/m
and the velocity of the electrons.
