Teltron Dual Beam Tube Manufacturer,Supplier and Exporter
Product Code : SCL-AAN-11412
The electron beam source is an oxide cathode heated indirectly via a heating coil.
The dual beam tube is a partly evacuated electron tube, filled with helium at low pressure and equipped with both axial and perpendicular electron guns.
The electron beams are perpendicular to one another and a common deflector plate is provided for both guns.
The dual beam tube can be used to determine the specific charge e/m from the diameter of the path followed by Science Lab India electrons fired into the tube from a perpendicularly mounted gun with a vertically aligned magnetic field and observation of the spiral path followed by electrons fired axially into a coaxial magnetic field.
The electron paths show up as a fine, slightly greenish beam due to impact excitation of the helium atoms. Requires a 300 V or 500 V DC power supply.
