DESCRIPTION

The innovation concerns the development of phosphate glasses intrinsically photosensitive and their drawing in the form of fiberglass for dosimetry systems.

BENEFITS

  • Sensitivity of the fiber to X ray, Alpha, Gamma, Electrons and Protons,
  • Glass transition temperatures (Tg ~200-400 °C) and low temperature drawing (TFibrage ~500-700 °C) of the phosphate glasses,
  • High active surface,
  • Possibility of new shapes like : The matrix allow the real-time positioning of the patient and the monitoring of the dose and / or the energy deposited,
  • Wide, lightweight and potentially flexible dosimeters.
