Embodiment Construction
[0023] Below in conjunction with accompanying drawing, the present invention will be further described, as figure 2 As shown, a radiation detector with a scintillation crystal on a special light-emitting surface, including a scintillation crystal 1, a light sensor 2, a preamplifier circuit and a multi-channel analyzer 3, the surface of the scintillation crystal is provided with a reflective layer and an anti-reflection layer, and the reflective layer It is arranged on the surface S2 except the scintillation light exit surface, the anti-reflection layer is arranged on the scintillation light exit surface S1, and the scintillation crystal is Europium-doped calcium fluoride CaF2 (Eu) crystal.
[0024] CaF2 (Eu) europium-doped calcium fluoride is one of the conventional scintillation crystals known in the prior art. Its refractive index is 1.47 and its peak wavelength is 435nm. When the photons reach the end flashing light exit surface S1, affected by the transmittance of the lig...
