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 Dual Beam Tube D
Semi-evacuated electron tube filled with low-pressure
helium and containing a tangential and axial electron
gun. In the case of tangential bombardment and a perpendicularly aligned magnetic field, the fundamental
electron charge-to-mass ratio can be determined from
the diameter of the observed beam pattern. In the case
of axial bombardment and a co-axial magnetic field,
kinetic gas theory (e.g. impact excitation) and particle
collisions can be studied through observations of the
fine, luminescent beams resulting from excitation of the
helium atoms. Product includes tube only. Instructions included.
Other equipment for use with the Teltron tubes:
605-006 EHT Power Supply
261-031 Digital Meter with two shunts included
