The University of Arizona

Workshop on “Remote Operation Across the Pacific of Scanning Electron Microscopy and Optical Raman Spectroscopy Performed Simultaneously”

June 11th-13th, 2008

By: Prof. Supapan Seraphin, Director of University Spectroscopy and Imaging Facilities (USIF), Department of Materials Science and Engineering, seraphin@email.arizona.edu, and Steven Hernandez, USIF, sahernandez2@gmail.com, University of Arizona, Tucson, Arizona 85721

In collaboration with: Thailand Metal and Materials Technology Center (MTEC)

Objectives: The Introductory Workshop will provide the attendees (up to 100 people) with an overview of the basic principles, advantages, limitations, and applications of scanning electron microscopy (SEM) and Raman spectroscopy. The latest technology development of combining these two techniques will be introduced.

The Intensive Hands-on Training will provide attendees (15 people), who have worked directly with SEM and/or Raman spectroscopy, with a working knowledge and practical aspects of the combined techniques.
