2 John F. Mansfield North Campus Electron Microbeam Analysis Lab., University of Michigan 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. 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. 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. Teaching students to actually use a standard SEM in this environment is not practical. Lecture demonstrations to large classes (100 people) completely impractical. Lecture demonstrations to large classes (100 people) completely impractical.

3 John F. Mansfield North Campus Electron Microbeam Analysis Lab., University of MichiganEMAL U of M SEM Training typically one-on-one.

4 John F. Mansfield North Campus Electron Microbeam Analysis Lab., University of Michigan Remote control SEM Training typically one-on-10 to 100+. This classroom at Lehigh University during one of the Microscopy Short Courses held there every year.

8 John F. Mansfield North Campus Electron Microbeam Analysis Lab., University of Michigan Application: SEM in the Classroom at Emerson School John Mansfield operating the North Campus XL30FEG from the middle school computer classroom at Emerson School, Ann Arbor. Note: Control also possible across ISDN connection (128kbps), Mansfield has done remote control from his house!
