Teltron Dual Beam Tube S

The Teltron Dual Beam Tube S consists of a part-evacuated electron tube filled with helium gas and accompanied by a tangential and axial electron gun. Suitable for measuring the charge e/m after a tangential bombardment with a perpendicularly aligned magnetic field of the diameter of the filament beam. The beam can be used to observe the spiral paths of the electrons in the event of an axial bombardment and a co-axial magnetic field. The luminescent beams render the electron paths visible due to the impact caused by the excitation of helium atoms.
