SCINTILLATION MATERIAL FOR REGISTRATION OF HIGH ENERGY IONIZING RADIATION Russian patent published in 1996 - IPC

FIELD: crystalline materials. SUBSTANCE: method involves the use of high-frequency (ρ_o= 6,12 g/cm³) and radiation-resistant (10⁹ rad) materials which can be used as scintillators in registration systems of ionizing radiation, in part, in electromagnetic calorimeters. Monocrystalline materials are the solid solution on the base of CdF₂ with fluoride RF₃ addition where R - cerium, lanthanum or their mixture corresponding empirical formulas Cd_1-xCl_xF_2+x, Cd_0,99La_0,01F_2,01, Cd_0,98La_0,01Cl_0,01F_2,01,. Other material is the solid solution on the base of monocrystralline cerium fluoride with cadmium fluoride addition corresponding empirical formula Cl_0,995Cd_0,005F_2,995. Monocrystals were grown in graphite crucibles under fluorinating atmosphere. EFFECT: enhanced quality of material. 3 cl, 3 dwg, 1 tbl
