====== Electron Diffraction ====== {{:physicsdemos:modern_physics:quantum_effects:electron_diffraction.jpeg?400|}} A commercial apparatus directs an electron beam at a a polycrystaline graphite target. The resulting diffraction pattern is visible on a phosphor screen. The energy of the incident electrons may be varied to show how the diffraction pattern changes with energy. {{ :physicsdemos:modern_physics:quantum_effects:electron_diffraction_20200417143218.mp4 |}} Apparatus Location: from labs PIRA DCS 7A60.10
