YAP(Ce) Scintillation Crystals
Yttrium Aluminium Perovskite (Cerium) - YAP(Ce) YAlO₃:Ce - is fast, mechanically robust scintillator with relatively high brightness.

YAP(Ce) scintillator crystal strengths:
  • Fast with a decay time of 28ns
  • Good stopping power with a density of 5.37 g/cm³
  • Good performance at high temperatures, -0.01%/ºC
  • Mechanically robust characteristics and are non-hygroscopic
  • No cleavage planes, so can me easily machined into various shapes and geometries

YAP(Ce) scintillator scintillator crystals, issues to be noted:
  • TBA

Yttrium Aluminium Perovskite (Cerium) - YAP(Ce) - scintillator crystals are useful in diverse applications such as:
  • Medical imaging
  • Geological logging
  • Specialist applications in high energy, nuclear, space and medical physics
