Electron Deflection Tube D Experiment Kit

The Electron Deflection Tube D Experiment Kit gives you all the equipment you need to carry out experiments on electrons, including the Electron Deflection Tube itself, a tube holder, a pair of Helmholz coils and three power supplies. 

About the Deflection Tube D

The Deflection Tube D consists of a highly evacuated electron tube, an electron gun and a fluorescent screen. These are set at an incline relative to the beam so the beam's path is rendered visible and the electrical and magnetic fields can be examined and studied. The electric field can be adjusted to cancel out the magnetic deflection, making it possible to determine the specific charge e/m, or the velocity of the electrons.

About the Experiment Kit

The Electron Beam can be deflected electrically in the electric field of the built-in plate capacitor, and can be combined with the Helmholz Pair of Coils D to deflect the beam magnetically. The kit comes with both two high voltage power supplies and a DC power supply, to enable this experiment to be performed.
