Dual Beam Tube S

Part evacuated electron tube, filled with neon 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 neon atoms.
Max. filament voltage:        7,5 V AC/DC
Anode voltage:                    approx. 150 V DC
Max. anode current:            < 30 mA
Max. deflection voltage:     50 V DC
Glass bulb:                           approx. 130 mm diam.
Total length: approx. 260 mm
