Description

Teltron Discharge Tubes
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. 

Teltron Electron Diffraction Tube D
Highly evacuated electron tube for demonstrating the
wave nature of electrons through the observation of
interference caused by passage of electrons through a
polycrystalline graphite lattice (Debye-Scherrer diffraction)
and rendered visible on a fluorescent screen. Also intended
for determining the wavelength as a function of the
anode voltage from the radii of the diffraction rings and
the lattice plane spacing of graphite, as well as confirming
de Broglie’s hypothesis. Instructions included.

Other equipment for use with the Teltron tubes:

605-006 EHT Power Supply
261-031 Digital Meter with two shunts included
