MANUFACTURE OF SCINTILLATOR

摘要

PURPOSE:To manufacture a high-sensitivity scintillator of small size and high energy resolution by filling cut grooves in a BGO crystal with a reflection material with high density. CONSTITUTION:Lattice-like cut grooves 4 and 5 orthogonal to the scintillation light emission plane 2a of a BI4Ge3O2 crystal 2 and orthogonal to eachs other are formed from the above-mentioned emission plane 2a. The cut grooves 4 and 5 are filled with a resin solution containing a reflection material powder 6 under depressurization of 1.5X10<10> Pa or less and cleared of solvent by depressurization to form a reflection layer 7.
