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 using two methods: 1) electrically using electric
field of the built-in plate capacitor, or 2) magnetically using
external Helmholtz Coils . Also determine the fundamental
electron charge-to-mass ratio (e/m) and study mean electron
velocities using field cancellation.
