New developments at the INE-Beamline for actinide research at ANKA

The INE-Beamline for actinide research at the synchrotron source Angstroemquelle Karlsruhe (ANKA) completed its first year of operation in October 2006. Experiments on radioactive samples with activities up to 106 times the limit of exemption at X-ray energies from around 2.1 keV (P K-edge) to 25 keV (Pd K-edge) are possible. Three recent instrumental developments at the Nuclear Waste Disposal (INE)-Beamline are presented: a Quick-XAFS mode of operating the Lemonnier-type monochromator in fixed exit for time-resolved experiments, total electron yield detection, and the use of one-dimensional compound refractive lenses, fabricated at the Institut fuer Mikrostrukturtechnik (IMT) at Forschungszentrum Karlsruhe (FZK), as a virtual slit for surface sensitive X-ray studies. Future upgrades for lowering the attainable energy, installing a microfocus option, and commissioning a cryostat for radioactive samples are planned
