Electron Diffraction Experimental Apparatus for Advanced Physics Lab

The Electron Diffraction Experimental Apparatus for Advanced Physics Lab is designed to demonstrate the wave nature of electrons and verify the fundamental principles of quantum mechanics. Based on the concept of wave-particle duality, the apparatus enables students to observe electron diffraction and experimentally confirm that electrons exhibit both particle and wave characteristics. The system features a specially designed electron diffraction tube with a transparent viewing window for clear observation. An electron gun generates and accelerates electrons toward a thin polycrystalline gold foil target. As the accelerated electrons interact with the crystalline structure, distinct diffraction rings are produced on a fluorescent screen, allowing both qualitative observation and quantitative analysis. With its precise construction and high-quality diffraction tube, the apparatus provides bright, sharp, and stable diffraction patterns, making it an ideal teaching and research instrument for physics laboratories.
