Mar 08,2021 by Edulab

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

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