Plug in the laser and aim it at the wire, maximizing the intensity and spread of the diffraction pattern. Use a lab jack to elevate the fringe pattern to a screen, if necessary. Repeat step 1 to 3 for ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

Fast, precise and stable nanopositioning and metrology are critical for the development of nanoscale structures, particularly in the semiconductor industry. Present measurement techniques that ...
