Scanning Electron Microscopy & Its Practical Applications - Winter Semester 1999

Proposed boilerplate for Physics 307: Scanning Electron Microscopy (3)
Prerequisite: Consent of Instructor. A lecture/laboratory study of scientific research techniques using scanning electron microscopy (SEM). Course includes electron gun/lens optics, beam-specimen interactions, image formation, associated x-ray techniques, and analysis of images. Two hours lecture and two hours laboratory per week.

This course is geared towards training students to effectively use an SEM and its associated X-ray analytical equipment. The theory part will cover the basic physics of Scanning Electron Microscopy, so that information obtainable from specimens is understood. The lab part deals with operation of such instruments, including the two turbo-pumped Cambridge SEM's in our lab. This course is prerequisite for a course on Transmission Electron Microscopy, to follow.

To take the course, apply to enroll by e-mail or in person with the course instructors. Slots are still open for this semester. Even after all slots in the course are filled, an e-mail application will let us know that you are interested. Credit in Physics reading, special topics or research courses, assuming that your participation meets the appropriate requirements, will then be available by registration with the University after the fact, e.g. for the corresponding course in summer or spring 1998. The possibility for similar credit through the Chemistry or Biology department is under discussion as well.

What's New?
  • Field-Width vs. Working-Distance for various S240 Mag-Settings at Low and High kV.
  • A plot to infer Working-Distance from Focus-Setting on our S240.
  • Updated Winter 1999 Course Announcement.
  • This course is on-deck for Winter Semester 1999, along with Biology 392 (Topics in Electron Microscopy) which will be using our transmission and scanning electron scopes!
  • Our TEMs include a Hitachi H600w/STEM & Philips 430STw/EDS-EELS, both under service contract (9/98).
  • Our SEMs include a Cambridge S250 & S240w/EDS, both up and running (6/98).
  • See the developing course pages for our TEM course (targeted for fall 1998), and our SPM course (to be prototyped in summer 1998).
  • Draft description of a possible summer workshop series targeted toward analytical service clients rather than operators.
  • Schematic on the focussing effect of magnetic lenses.
  • Our first meeting was Saturday 14 Feb 1998 in Molecular Room 101 at 9am. If you are still interested, stop in for a visit next Saturday morning, or let us know by e-mail.
  • Richard Anderson ordered his copy of the book from Amazon by overnight mail. However, their stock may be limited. I have also taken steps to get a lab copy, and have the bookstore fly in 10 copies of the text. However, I don't yet know how long that will take.
  • Haresh Siriwardane of MEMC Electronic Materials will be teaching the course, with help from collaborators primarily at UM-StL and Monsanto.
  • This course now has a university-wizarded webpage and discussion area.
  • Ask in class for the discussion password if you don't have it. The pre-course login ID is [Physcs381.E09], while the pre-course password is [Physcs381.E09]
