GARNET-STRUCTURED CRYSTAL FOR SCINTILLATOR AND RADIATION DETECTOR USING SAME Russian patent published in 2017 - IPC C09K11/78 C09K11/80 G01T1/202 

FIELD: physics.

SUBSTANCE: garnet-structured single crystal for the scintillator is represented by one of the general formulas (1), (2) or (3). Gd_3-x-yCe_xRE_yAl_5-zGa_zO₁₂ (1), where 0.0001≤x≤0.15, 0≤y≤0.1, 2.5<z≤3.5, RE - Y and/or Yb, and the content amount ratio Gd, Ce, RE to the content amount Al and Ga is 3:5. Gd_3-a-bCe_aLu_bAl_5-cGa_cO₁₂ (2), where 0.0001≤a≤0.15, 0.1<b≤3, 3<c≤4.5 and 0≤3-a-b. Gd_3-p-qCe_pRE'_qAl_5-rGa_rO₁₂ (3), where 0.0001≤p≤0.15, 0.1<q≤1.5 1<r≤4.5, 0≤3-p-q, RE' - Y or Yb, and the content amount ratio Gd, Ce, RE' to the content amount Al and Ga is 3:5. The radiation detector includes the said scintillator and a light receiver from the scintillator.

EFFECT: Improving the detector operation.
