Электровакуумный прибор с узким пучком, на подставке для подключения
The Fine Beam Tube is for examining the deflection of electron beams in a uniform magnetic field using a pair of Helmholtz coils and for the quantitative determination of the specific charge of the electron.
Experiment topics:
• Deflection of electrons in a closed circular path inside a magnetic field.
• Determination of specific charge of an electron e/m.
The evacuated glass tube is integrated with an electron beam system consisting of:
• an indirectly heated oxide cathode
• a Wehnelt cylinder and a perforated anode
• residual gas atmosphere with set gas pressure
• integrated measurement marks for parallax-free measurements
The gas atoms are ionized along the electron path and produce a sharply defined, visible fluorescent beam. The tube is mounted on a base with color coded connectors.
Gas filling: Neon
Gas pressure: 1.3 x 10-5 hPa
Filament voltage: 5 - 7 V DC
Filament current: < 150 mA
Wehnelt voltage: 0 - -50 V
Anode voltage: 200 - 300 V
Anode current: <0.3 mA
Circular path diameter: 20 - 120 mm
Division spacing: approx. 20 mm
Tube diameter: approx. 160 mm
