Apertures and Diffraction Gratings
Electron Diffraction Tube, Type D
Highly evacuated tube for demonstrating electron diffraction and the wave nature of electrons. Its electron gun produces a focused beam that passes through a graphitized carbon target, forming two concentric diffraction rings on the fluorescent screen; a magnet is included for beam-path adjustment.
