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. 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 electric connections. 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



Specifications:
  • Gas filling: Neon
  • Gas pressure: 1.3 x 10-5 hPa
  • Filament voltage: 4 - 8 V AC/DC
  • Filament current: 300 - 450 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
