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
connections on the stand rather than the tubes.
Please note the ranges are not interchangeable.
Teltron Thomson Tube S
High-vacuum electron tube with high-accuracy electron
gun and ruled target phosphorescent screen. Determine
the fundamental electron charge-to-mass ratio (e/m),
study mean electron velocities using field cancellation,
and explore electron optics using this tube.
The electron beam trajectory can be manipulated using two methods:
- Deflection induced by the electric field of the built-in
plate capacitor, or
- Magnetically using externalHelmholtz Coils S. .
