HacDC is in the process of refurbishing a scanning electron microscope: a Cambridge Stereoscan 200.

SEM in workshop

Current Status

March 30th: Moving complete! The SEM is now in the workshop

March 29th: Awaiting pick-up and installation (March 29th and 30th).

March 23rd: A space in the workshop has been cleared. Photo: http://i.imgur.com/BDNWL5z.jpg

Maintenance Information

Maintenance and repair logs will be kept on an ongoing basis. For previous status and repairs, see:

Useful information

Resources

  • The original S200 operating instructions will be available at the space in a three-ring binder near the machine.
  • If possible, members will also have access to a PDF copy of Scanning Electron Microscopy - A Student's Handbook, 1980, self-published by Michael Postek, et al. This book was widely used by microscopists and is still regarded as a good learning reference, but the original binding is rare and prone to falling apart. It might be possible to use the PDF copy for private, educational use.

Contacts

We'll have a list here of HacDC members who are responsible for the SEM, including people that should be notified about problems.
