Program
Transmission electron microscopy (TEM) resolves details of natural and man-made structures at the micrometer, nanometer, and even sub-nanometer scale. Energy filtered TEM (EFTEM) and electron energy loss spectroscopy (EELS) are the ideal analytical partners to the high spatial resolution provided by TEM in both the conventional and scanned (STEM) imaging modes.
The School provides an introduction to the capabilities of EFTEM and EELS for users of Gatan energy filters (GIF™) and spectrometers (Enfina™). It also provides the necessary theoretical background and hands-on training that current users need to get the most out of their Gatan EFTEM and EELS instruments and software.
Topics
• Fundamentals of energy-filtered imaging in TEM and EELS
• Principles of operation of Gatan EFTEM and EELS systems
• Optimization of EFTEM and EELS data acquisition
• Quantification of elemental composition
• Other information provided by EFTEM/EELS and how best to extract it
• Use of EELS signals to form maps of elemental and chemical composition
• EFTEM and STEM EELS spectrum imaging techniques
• Identification of material phases via EELS fine structure mapping
• Formation of spatially resolved maps of dielectric properties
• Applications to biological and physical science specimens
Format
Each day's activities include three 45-minute lectures, two 90-minute demonstration labs, and two 90-minute practical lab periods. Lab sessions are split evenly between data-acquisition techniques in the TEM lab and data analysis procedures at separate computer workstations running the Gatan Microscopy Suite (GMS™) software. The lectures and demonstration labs are led by expert instructors. The practical lab periods, supervised by Gatan specialists, provide hands-on training for participants to develop their EFTEM and EELS techniques. Participants are strongly encouraged to bring their own documented and nonproprietary specimens for this purpose.
A full range of Gatan EFTEM and EELS instrumentation and software will be available during the course: Gatan Tridiem GIF, with model 777 STEMPack system installed on JEM 2100F TEMs.
The number of participants is limited to 20, to ensure the best quality hands-on sessions for all attendees.
Costs and registration
The cost is approximately 6000SEK; the actual cost has not yet been finalized. Lunches and refreshments will be included and also a “celebration dinner.” Participants are responsible for their own hotel and travel arrangements and costs. Non-local participants should plan on arriving in Stockholm on Monday, May 19, 2008 to allow for the start of school at 10:00 am on Tuesday, May 20, 2008.
