LATEST VERSION of aXis2000 - 25 July 2017

The Hitchcock group develops new instruments, methods and applications of inner shell excitation spectroscopies and microscopies for analysis of advanced materials. We are particularly active in the application of X-ray microscopy to fuel cell materials, polymers, nanostructures, biomaterials, magnetotactic bacteria, environmental studies. A focus at present is in situ and operando methods, such as in situ flow electrochemistry, investigation of polymer electrolyte membrane fuel cell electrodes under realistic (T,RH), and studies of peptide - model lipid membrane interactions. We also continue using electron impact and synchrotron methods to advance our understanding ot the fundamentals of Inner shell excitation spectroscopy of gases, surfaces, solids and liquids

A common theme of all projects is the development of new experimental techniques based on electron impact and X-ray absorption phenomena, and optimization of their application to a wide variety of chemical, physical and materials problems. Collaborations with researchers in industry, government, and other universities play a large role in our approach to promote interest in, and practical uses for, inner-shell spectroscopies. Typically, these collaborations combine the group's expertise in X-ray and electron impact spectroscopic analysis with chemical, materials or physical problems motivated by the collaborating group.

Our group has helped develop the most advanced analytical soft X-ray microscope in the world (a scanning transmission X-ray microscope at the Advanced Light Source in Berkeley, and lead the mplementation of STXMs at the Canadian Light Source (CLS) in Saskatoon). We are exploring new applications on a monthly basis. Over the past 5 years, in collaboration with instrument developers and scientists at the CLS, we have helped develop a new cryo-STXM with capabilities for cryo-spectro-tomography. We are helping to develop applications of soft X-ray ptychography.

The CLS soft X-ray spectroscopy beamline (SM) features two scanning transmission X-ray microscopes (STXM) and an X-ray photoemission electron microscope (X-PEEM) on separate branch lines of a high performance plane grating monochromator beamline, illuminated by an elliptically polarized undulator.

Please explore the pages of this web site. It contains highlights of our research, information about group members, opportunities for research positions, a list our publications (with links to pdfs), and links to tools we provide to others - aXis2000, BAN, the Core Excitation Bibiography and Database (~600 spectra of ~400 gas phase compounds!!), and a X-ray microscopy bibliography as well as links to related sites.
