Current Scintillator Technology

• Security Screening System uses CdWO₄ crystals for scintillating detectors
  • Problem: of about 40% X-ray radiation damage and low luminescent intensity.
• CTI PET medical system uses Lu₂SiO₄ crystals for detector arrays.
  • Problem: Lu is very expensive and the luminescent wavelength of LSO is too short (420nm).

Our Scintillator Technology

Solving major problems: Doped CWO reduced the radiation damage from 40% to under 5%. High quality doped CWO crystals Bi doped new crystal has 50% increase in light out intensity in green-yellow wavelength
