CERAMIC PHOSWICH-DETECTOR WITH ALLOYED OPTICAL ELEMENTS, METHOD OF ITS PRODUCTION AND PRODUCTS CONSISTING OF IT Russian patent published in 2017 - IPC G01T1/20 

FIELD: chemistry.

SUBSTANCE: scintillator contains a large number of garnet compositions in a single block having a structural formula (1): M¹_aM²_bM³_cM⁴_dO₁₂, in which O is oxygen, M¹, M², M³ and M⁴ is the first, the second, the third, and the fourth metal, which differ from each other, wherein the sum of a+ b+c+d is about 8, where "a" is from 2 to 3.5, "b" is from 0 to 5, "c" - from 0 to 5, "d" - from 0 to 1, where "b" and "c", "b" and "d" or "c" and "d" can not both be zero at the same time, in which M¹ is a rare earth element, including gadolinium, yttrium, lutetium, or a combination thereof, M² is aluminium or boron, M³ is gallium, and M⁴ is a co-dopant; where two compositions having the same structural formulas are not disposed adjacent to each other and where a single unit is devoid of optical interfaces between the various compositions.

EFFECT: increasing the time resolution.
