Teltron Dual Beam Tube D
The Teltron Dual Beam Tube D is a helium-filled tube with a tangential and axial electron gun.
Experiment:
• Determine the specific charge of the electron
• Use the diameter of the beam in an orthogonal magnetic field to determine the charge-to-mass ratio
• Observe spiral paths in a co-axial magnetic field
Specifics:
Gas filling: Helium
Heating: < 7.5 V AC/DC
Anode voltage: 0 - 100 V DC
Anode current: typically 30 mA
Deflection voltage: 0 - 25 V DC
Glass bulb: approx. 130 mm Ø
Total length: approx. 260 mm
