Yttrium aluminum perovslit activated Cerium is a fast, mechanically amd chemically resistant scintillation material.   Mechanical properties enable precise machining.   Scintillator has very low energy secondary Xray emission, which is advantage for imaging applications.   YAP:Ce detectors are used for Gamma and Xray counting, electron microscopy, electron and Xray imaging screens.   Scintillation and mechanical properties enable usage in tomography systems.
below shown photograph exhibits an example of 1mmx1mmx20mm tiny bar shape YAP:Ce crystals for array use.
YAP:Ce crystals can be machined to thin plate form by particular requests.   machinable thickness depends to the crystal dimensions.   please contact.
