HacDC is in the process of refurbishing a scanning electron microscope: a Cambridge Stereoscan 200.
 Current Status
Cleaning and assessment in progress.
June 23rd: Summary. Roughing pump works, seals adequate to fire turbo. Probably just needs cleaning and testing, similar in scope to commissioning a new 3D printer. -mirage335
See Stereoscan_Operators_Log for details.

Previous owners (757 Labs, another hackerspace) attempting repairs compiled some information at:

 Additional Resources
- The original S200 operating instructions are 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.
