Demo Title:
Crystal Structure using Electron Diffraction
Determination of lattice structure
Area of Study:
Modern Physics
5 kV Power Supply, Electron Diffraction Tube (Tel-Atomic), Tube Stand, Camera and Power Supply.

Set the unit up as shown and according to the circuit diagram. Turn on the power supply and allow a short time for the filament to warm up. Push up the slide switch and observe the diffraction rings form. Aim the camera at the screen on the end of the tube. See the information in the files about tube parameters and target makeup.
