Ion beam laboratory

Ion beam analysis laboratory

The areas of research within the ion beam analysis laboratory are the physical processes taking place in solid matter during and after irradiation of energetic ions. These areas involve

  • Interaction and slowing-down of energetic ions in solids
  • Ion irradiation induced effects on the structure of matter
  • Interaction of defects, host atoms, and implanted atoms
  • Diffusion and solubility of impurity atoms
  • Production of new materials
  • Analysis of ion-implanted and irradiated Materials

Ion beam technology offers opportunities for research and technology of modifying various characteristics of metals, semiconductors, ceramics, plastics and organics, and of fabricating new materials from them.

The experimental facilities of the laboratory include:

  • TAMIA, a 5MV tandem accelerator, which is mainly used for
    • Accelerator Mass Spectrometry (AMS)
    • Elastic Recoil Detection (ERD)
    • In situ irradiation and PAS/electrical characterization of materials at variable temperatures
    • Rutherford Backscattering
  • KIIA, a 500kV implanter
    • Rutherford Backscattering including channeling
  • Sputtering device for serial sectioning of radiotracer implanted diffusion samples
