KIT-INE, Karlsruhe Institute of Technology - Institute for Nuclear Waste Disposal, Karlsruhe, Germany

The INE-Beamline (INE-BL) at the synchrotron source ANKA located on the KIT North Campus in close proximity to INE controlled area labs is dedicated to actinide speciation investigations related to geochemical aspects of nuclear waste disposal as well as applied and basic actinide research.

Investigations on non-fissile radioisotopes up to 106 times the legal exemption limit and fissile radioisotopes (Pu-239, U-235) up to 200 mg, contained within two layers of protection, are possible at the INE-BL. A special protocol for working with radioactive samples at the INE-BL exists and is supervised by INE’s own radiation protection officers.

The experimental instrumentation at the INE-BL has a modular design (see Table), with emphasis on X-ray spectroscopic investigations. The available energy range (~2.1-25 keV) covers key energy regions of interest for investigations of actinides (L3 edges ~16 – 20 keV) and lanthanides as their homologues (L-edges ~5.5 – 11 keV).

Beamline specifics

  • Photon energies from the K edge of P (2.1 keV) to the Pd K-edge (25 keV)
  • Compact Lemonnier-type double crystal monochromator (DCM) built at the University of Bonn, allowing fixed exit operation and fast crystal changes (presently available Si(111), Si(311), and Ge(422), InSb(111))
  • Collimating and focusing mirrors for a sub-mm beam dimension at the sample position. Auxiliary µ-focusing with single bounce and polycapillary half-lenses available
  • Sample positioners / goniometers and auxillary slits for standard XAFS and surface sensitive GI-XAFS
  • Johann spectrometer for high resolution emission measurements (PFY-XANES, RIXS)
  • Detectors available: fluorescence detectors (5 pixel high purity germanium, silicon drift detector) with digital detector read-out, total electron yield (TEY), image plates for µ-XRD, small area high resolution CCD, a calibrated PIN diode, ionization chambers
  • Various sample environments available, including liquid N2 cryostat, spectro-electrochemical cell, inert gas containments
  • Infrastructure for working with radioactive samples including sealed media feed-through chicanes, ventilation / filter system, hutch access through lock-room with hand/foot-contamination monitor
