Product details Experiment Topics:
Deflection of electrons in a closed circular path within a magnetic field Determination of specific charge of an electron e / m To investigate the deflection of electron beams in a uniform magnetic field using a pair of Helmholtz coils (508050) and for the quantitative determination of the specific charge of the electron e / m.
Consisting of a glass sphere with integrated electron beam system, consisting of an indirectly heated oxide cathode, a Wehnelt cylinder and a perforated anode, in a neon-residue gas atmosphere with precisely adjusted gas pressure and with integrated markers for parallax-free determination of fine beam diameter. Gas atoms are ionised along the electron path and produce a sharply defined, visible fluorescent beam.
Fixed-base mounted tube with colour-coded connections.
PLEASE NOTE: keep the specific current and voltage limits for the filament, once defective it cannot be repaired.
Specifications:
Specifications: Gas filling: Neon Gas pressure: 1.3 x 10-5 hPa Filament voltage: 5 - 7 V DC Filament current: <150 mA Wehnelt voltage: 0 to -50 V Anode voltage: 200 - 300 V Anode current: <0.3 mA Circular track diameter: 20 - 120 mm Marker spacing: approx. 20 mm Tube diameter: approx. 160 mm Dimensions 115 x 115 x 35 mm Weight: approx. 820 g
