Philips XL30 FEG

Location: 425 Space Research Building
Contact: John Mansfield or Kai Sun
Instructions: Philips XL30FEG PDF Handbook
Acknowledgments: This instrument was funded from a variety of sources, but the largest portion of the funds came from an AFSOR MURI headed by Ron Gibala (DOD-G-F49620-93-1-0289, Center for Advanced Structural Metallic Materials). Other monies were provided by the College of Engineering and the Department of Materials Science and Engineering.

Scanning Electron Microscopy: The Philips XL30 Scanning Electron Microscope (SEM) is one of a generation of SEMs that is completely controlled from a computer workstation. The XL series instruments are controlled by a personal computer running Microsoft Windows NT. The EMAL instrument employs a thermally assisted Schottky field emission gun for high intensity probe formation. This makes the instrument ideal for both imaging and microanalysis.
