Current Research

  • Application of ion-beam based techniques to a wide range of problems in materials science, life science and solid-state physics.
  • Development of Nuclear Microscopy and the various analytical and lithographic techniques associated, e.g. ERDA, IBIC, RBS, Proton Beam Writing.
  • Development and applications of high resolution (magnet spectrometer) RBS and ERD, quantitative techniques for the analysis of ultrathin film systems.
  • Proton radiobiology for the further development of proton therapy modalities for cancer therapy.

CIBA is a multi-disciplinary research centre, we aim to develop new technologies based on fast protons and light ions (alphas, N ,O), and to undertake research into novel cutting edge ion-based applications.

  • Currently, CIBA is the only accelerator group, globally, able to focus MeV protons to spot sizes below 20 nm. We are using this technology in a range of ongoing projects.
  • In a collaboration with the National Cancer Centre, Singapore we explore ways to enhance the efficiacy of Proton Beam Therapy (PBT), the most advanced cancer radiotherapy available, which is rapidly being introduced in Singapore. CIBA groups operate two beamlines, one for in vitro single hit irradiation of sub-cellular structures, at resolutions below 500nm, and the other for rapid large area irradiation of millions of cells in a monolayer configuration.
  • A wide range of applications of Ion Beam Analysis and Nuclear Microscopy research is ongoing at the dedicated beamlines at CIBA, as shown above.
