Description

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.
Semi-evacuated electron tube filled with lowpressure
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 thehelium
atoms. 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.
