MarkeTech PWO (Lead tungstate, PbWO4) Scintillator Crystal  (discontinued **)
Categories: Ceramic; Oxide

Material Notes: Lead tungstate PbWO4 (PWO) is a new "heavy" highly efficient and "fast" scintillator for high energy physics. It has the shortest radiation length and Moliere radius among the known scintillators, satisfactory light yield for this energy range, high radiation stability. Production technology which is under continuous development allows to prepare uniform scintillators ensuring high energetic and special resolution of the detecting assembles on accelerators.
