Teltron Perrin Tube S
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:

  • Electrically using electric field of the built-in plate
    capacitor, or
  • Magnetically using external Helmholtz
    Coils S. Also determine the fundamental electron chargeto- mass ratio (e/m) and study mean electron velocities using field cancellation. Instructions included.
