Rationale: Why SEM Remote Control? Want to use SEM in MS&E undergraduate labs & lecture demonstrations. Problems: MS&E undergraduate classes number ~40 at UM. Limited space in SEM labs usually means only two or three people can view screen at any one time. Teaching students to actually use a standard SEM in this environment is not practical. Lecture demonstrations to large classes (≥ 100 people) completely impractical. John F. Mansfield North Campus Electron Microbeam Analysis Lab. , University of Michigan
