DESCRIPTION:Speakers: Christoph Lenz (ANSTO)\nThe investigation of radiati
 on damaged or metamict minerals and their synthetic analogues has increase
 d appreciably over the past two decades\, stimulated by the potential use 
 of mineral-like ceramics as waste forms for the immobilisation of reproces
 sed spent nuclear fuel and other radioactive waste. In this research field
 \, however\, a fast and inexpensive technique operating in the micrometre 
 range may open up new opportunities in the characterisation of radiation d
 amage.\n\nWe present first results of a heavy-ion (Au) irradiation-study o
 f the important nuclear waste-form matrices zircon (ZrSiO4)\, xenotime-(Y)
  (YPO4) and zirconolite (CaZrTi2O7). Bulk\, poly-crystalline ceramics were
  irradiated with accelerated heavy ions (Au) with energies up to 35 MeV. C
 omparably high heavy-ion energies are chosen to ensure irradiation penetra
 tion-depths of 4 - 5 µm accessible to the spatial resolution of optical c
 onfocal spectrometers.\n\nhttps://events01.synchrotron.org.au/event/51/con
