Description

The Teltron range of demonstration discharge
tubes has been designed to show the properties
of the free electron.
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.
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 fieldof 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.
Other equipment for use with the Teltron
tubes:
EHT Power Supply.
Digital Meter with two shunts included.
Shrouded Test Lead Red.
Shrouded Test Lead Black.
