Computing Facilities

The Central Facility for Electron Microscopy has diverse computing capabilites. These include six personal computers and several specialized programs and hardware capable of a variety of specialized Electron Microscopy tasks such as aquisition of xray data or imges. There are also general-use programs for analysis.

The use of these computers is generally tied in with a particular microscope but two computers, one Mac and one PC-compatible, are available for more general use to the users of the Facility.
