  • Deflection of electrons in a closed circular path inside a magnetic field.
  • Determination of specific charge of an electron e/m.

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 e/m. Glass vessel with integrated electron beam system, consisting of an indirectly heated oxide cathode, a Wehnelt cylinder and a perforated anode, in neon residual gas atmosphere with precisely set gas pressure and with integrated measurement marks for parallax-free determination of the diameter of the fine beam. Gas atoms are ionized along the electron path and produce a sharply defined, visible fluorescent beam. Tube mounted on base with color coded connectors.
The magnetic field is provided by a set of Helmholtz coils, and the entire system is powered by a single power supply.
