Teltron Discharge Tubes
The Teltron range of demonstration discharge tubes
has been designed to show the properties of the free
The D range is the original Teltron range with connections
fixed on the tubes. The S range is a newer range with
connections on the stand rather than the tubes.
Please note the ranges are not interchangeable.
Teltron Electron Deflection Tube D
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 D. 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. Instructions included.
