Dual Beam Tube S

Party evacuated electron tube, filled with helium at low pressure, with tangential and axial electron gun. For determining specific charge e / m from the diameter of the filament beam in the case of tangential bombardment and a perpendicularly aligned magnetic field, and observing spiral paths of electrons in the case of axial bombardment and a co-axial magnetic field. The electron paths are rendered visible in the form of fine luminescent beams through impact excitation of the helium atoms.

• Max. anode voltage: 300 V DC
• Anode current: approx. 30 mA at 200 V (anode)
• Max. deflection voltage: 50 V DC
• Glass bulb: approx. 130 mm dia.
• Total length: approx. 250 mm
