Device for demonstrating the properties of electron beams
Device for demonstrating the properties of electron beams in school physics classes.
The gas-discharge tube contains a hydrogen generator and electron gun.
The device is based on the principle of interaction between the electron beam of the gas-discharge tube and the homogeneous magnetic field created by the Helmholtz coils. A beam of electrons is created in the gas-discharge tube by means of the electron gun. Its brightness, magnitude, and shape are controlled by the "Anode" and "Focus" knobs. The position of the electron beam relative to the magnetic field lines can be changed by rotating the gas-discharge tube around its axis. The magnitude of the magnetic field can be adjusted by changing the supply voltage of the coils.
