MarkeTech Yttrium aluminum garnet:Ce (YGA:Ce; Y3Al5O12) Scintillator Crystal  (discontinued **)
Categories: Ceramic; Oxide

Material Notes: Yttrium aluminum garnet activated by cerium is fast with excellent mechanical properties and is chemically resistant scintillator. Mechanical properties enable to produce YAG:Ce scintillation screens down to a thickness of 30 µm. YAG:Ce detectors are excellent for electron microscopy, beta and X-ray counting, electron and X-ray imaging screens.
