The laboratory houses a Jeol JSM-6480LV high-performance,
Variable Pressure Analytical Scanning Electron Microscope
with a high resolution of 3.0nm, along with EDS (Energy Dispersive
System) and EBSD (Electron Backscatter Diffraction) using
the Oxford Link system.
The low vacuum mode, allows for observation of specimens which
cannot be viewed at high vacuum due to excessive water content
or due to a non-conductive surface. Its asynchronous five-axis
eucentric stage with compeucentric rotation and tilt can accommodate
a specimen of up to 8-inches in diameter. Standard automated
features include Auto Focus/Auto Stigmator, Auto Gun (saturation
and alignment), and Automatic Contrast and Brightness.
Dynamic studies with microstructural information are possible
in the SEM, using mechanical testing apparatus and/or heating
stages.
The SEM stage modules allows tensile, compression and/or bending
tests, with load ranges from less than 2N to 5000N. Software
control allows different modes of operation and micro-cracks
or other microscopic features can be followed as the test
progresses. Heated and heated/cooled grips, or platforms are
available for temperature dependent studies and tilted stage
and grip options are available for dynamic EBSD studies.
The SEM facilities are available for use by both members
of UCL Earth Sciences and external users.
