X-Ray Microscopy
- Installation at SLS: STXM Endstation (right), beamline exit slit system (center) and STXM control rack
Bruker ASC is offering interferometer controlled scanning transmission X-ray microscopes (STXM). Their design is based on the successful systems at the ALS that were jointly developed by NCSU, ALS, and McMaster University (Kilcoyne et al., J. Synchrotron Rad. 10 (2003), 125–136). By measuring the specimen transmission at dif-ferent photon energies, STXMs can provide quan-titative information on the specimen’s local elemental and chemical composition and magnetiza-tion with high spatial resolution. A first STXM has been installed by BASC at the Swiss Light Source and is operating successfully in three-shift user operation. A second system with a number of new developments is currently being realized for the MPI-MF Stuttgart and will be installed at BESSY beginning of 2009.
