Canadian Light Source

We would like to thank T. Bonli for assistance with the XRD and SEM analyses and J. Essilfie-Dughan for assistance with XANES analyses at the Canadian Light Source. This project was jointly funded by Cameco Corporation and NSERC through an IRC grant. 

A number of synchrotrons (including the National Synchrotron Light Source, New York, the Advanced Light Source, Berkley, and soon the Canadian Light Source, Saskatoon) operate mail-in crystallography services where a scientist can mail in crystals (prefrozen and mounted on loops) and data will be collected, processed (sometimes), and returned. This is becoming a method of choice, as it eliminates the need to travel to a synchrotron and speeds up the data collection procedure at the synchrotron also. 

Figure 17.2. Carbon NEXAFS spectrum of NOM from the Suwannee River (IHSS standard humic acid mounted on indium foil total electron yield using a dwell time of 200 msec and an exit slit of 50 xm, calibrated to CO at 287.38 eV, Canadian Light Source SGM beamline 11-ID.l) to show pre-edge features and the so-called edge . The spectrum is deconvoluted using a series of Gaussian curves (G) at energy positions of known transitions, along with a step function at the edge as described by Solomon et al. (2005).

Tsun-Kong) Sham received his PhD in Chemistry from the University of Western Ontario for the studies of Mossbauer spectroscopy. He was on the staff of the Chemistry Department at Brookhaven National Laboratory for ten years before returning to the University of Western Ontario in 1988 and is presently a Professor in Chemistry and the Scientific Director of the Canadian Synchrotron Radiation Facility at the Synchrotron Radiation Center, University of Wisconsin-Madison. He has been involved in synchrotron research since 1975, is a scientific member of the SRI-CAT at the Advanced Photon Source and a Senior Scientific Consultant for the Canadian Light Source (University of Saskatchewan, Saskatoon, Canada). 

Improved and more dedicated facilities are about to be commissioned at the ALS in Berkeley and BESSY-II in Berlin, and are imder development at the Canadian Light Source in Saskatoon. While there remain many scientific questions that can be addressed with the present performance of existing nexafs microscopes, improved capabilities and the increasing availability of nexafs microscopy will result in significant growth of applications in pol5uner science and related fields.
