Workshop on X-ray fluorescence imaging

How to plan and execute the perfect experiment

February 15th 2018

One-day workshop in Lund on February 15th 2018

Want to pinpoint chemical species in your samples? New or relatively new to the use of synchrotrons? We invite you to a one-day workshop from some of the foremost experts in their field.

Registration closed - this event is now fully subscribed

The workshop will involve introductory lectures on x-ray fluorescence imaging, followed by discussion in groups on how to plan and execute the perfect experiment. This is aimed at researchers who are interested in this exciting method, but have little or no experience with X-ray Fluorescence imaging. One of the outcome aims of the workshop will be to establish further LINXS-based projects on x-ray fluorescence imaging.

Relevant disciplines:
This type of imaging is very widely applicable to identify chemical species in a broad range of types of samples and sizes, in particular for:

Biology, Geology, Life Science, Materials Science, Nanoscience & Soft Matter

Main organiser: Martin Bech

Speakers:

David Paterson, Principal Scientist XFM, Australian Synchrotron
David has 15+ years experience in X-ray Fluorescence Microscopy and fast efficient scanning and XRF methods. David will describe some of the latest XFM methods and techniques such as XANES imaging and advice on best sample preparation and data analysis methods.

Chris Jacobsen, Professor, Department of Physics & Astronomy, Northwestern University
Chris is a world expert in X-ray microscopy and leads a research group focused on developing new methods in x-ray microscopy, and applying them to interesting problems in biology, environmental science, and materials science. Chris will give a tutorial introduction on X-ray fluorescence and microscopy, and also discuss some topics like fluorescence tomography (including alignment and self-absorption correction).

Karina Thånell (Beamline scienctist and project leader for STXM) & Jörg Schwenke (CXI Beamline scientist) at SoftiMAX, Lund University – They will provide expertise around what will be available at the SoftiMAX beamline and related soft X-ray facilities at MAXIV

Ulf Johansson, NanoMAX beamline project manager, Lund University – Ulf will provide the expertise around what is and will be available at the nanoMAX beamline and related facilities at MAXIV.
