Welcome to the Electron
Microscopy Facility at Trinity College
++++ Recipient of National Science Foundation Award for New SEM! ++++
The electron microscope (EM) is an important research-grade instrument that is
used to study materials at
the micro- and nano-structural level. EMs are used in medicine,
industry, and academic settings around the world.
In 1996, Trinity College
was awarded an NSF matching grant to build the nucleus for an interdisciplinary
Electron Microscopy Facility to serve all the
sciences. Today, that proposal has matured into the
present-day EM Facility at Trinity College, with two
transmission electron microscopes (one for life sciences and one for materials
sciences), a scanning electron microscope, analytical support instrumentation,
fully-featured sample preparation facilities, and both print and digital data
acquisition capabilities. The
resolution potential of the EMs at Trinity is measured in fractions of a
nanometer!
Trinity also created a new
full-time position in EM facilities management,
to build courses, develop methodologies, operate and maintain the laboratories,
and enable student and faculty researchers to make full use of the Facility.
That position is currently held by Ann Lehman, who serves as Director of the Facility. An Electron Microscopy Advisory Committee (EMAC) provides oversight.
