FEI Quanta 200 3D Focussed Ion Beam Workstation and Environmental Scanning Electron Microscope

Location: 422 Space Research Building
Contact: John Mansfield or Kai Sun or Haiping Sun
Instructions: Quanta 3D User's Operation Manual and TEM Cross Section Preparation on the Quanta 3D
Acknowledgments: Publications resulting from work on this instrument should acknowledge the support of NSF grant #DMR-0320740

Environmental Scanning Electron Microscopy: Although an Environmental Scanning Electron Microscope produces a scanned image similar to that of a regular scanning electron microscope, the environment of the sample chamber and the method of detecting the secondary electron signal are novel. The sample chamber is held at a pressure of typically between 1-20 torr.
