GFAG(Ce) Scintillation Crystals
GFAG(Ce) - Gadolinium Fine Aluminium Garnet is a newly developed scintillator. It is one of the brightest available scintillators with an emission peaking at 520nm. GFAG(Ce) has good stopping power, physically rugged and and well suited to a broad range of applications.

GFAG(Ce) - scintillator crystals are:
  • Relatively bright - emitting 45,000 photons/MeV
  • Good absorbers with good stopping powers - density 6.7g/cm³
  • Broadly emitting with a 520nm peak
  • Robust with good mechanically characteristics

GFAG(Ce) - scintillator crystals have the following issues which should be noted. They:
  • Have a light emission with a is good part above 500nm, a region where photomultipliers are less sensitive

GFAG(Ce) - scintillator crystals are useful in diverse applications such as:
  • Medical Imaging - PET, PEM, SPECT and Ct
  • Specialist applications in high energy, nuclear, space and medical physics
