Capabilities

Remote Electron Microscopy (REM)

Operate MAUC Instruments from your office using a PC or MAC.

A microscopy session

Benefits to User Program:

Several users at different locations participate in experiment
Students can gain microscopy experience remotely
Projects can be completed with reduced travel

How it is accomplished:

Software developed at ORNL controls microscope
Remote users/lurkers connected to the HTML by ISDN or internet
Remote operation using web browser (Netscape) or program such as Timbuktu
TelePresence provided by $100 digital camera and software such as CU-SeeMe

High Resolution Micrograph

The user controls:

Specimen positioning
Focus and magnification
Image acquisition
Astigmation correction

User sits in his office and uses his PC to acquire an image from the HF-2000 in the HTML (lower photo). Having placed the user's sample in the microscope, Materials Analysis staff member monitors the session, observing instrument control and image acquisition. High resolution image (photo to right) is transferred to user's computer.
