Cadmium tungstate (CdWO4)

Cadmium tungstate (CdWO₄or CWO) is a monoclinic crystal with Wolframite structure, which has good comprehensive scintillation performance. Its peak scintillation wavelength is 480nm (emission range 380-660nm), when subjected to γ The efficiency of radiation and X-ray irradiation is 13000 photons/MeV. CdWO4 crystal has the advantages of high luminescence efficiency, short afterglow time, large X-ray absorption coefficient, strong radiation damage resistance, and high material density, and is widely used in nuclear testing γ In camera, X-CT, high-energy physics, container detection and other fields, its combined application with B4C can form a compact gamma ray and Neutron radiation detector. Meanwhile, CdWO4 crystals can be used to detect rare nuclear processes, such as double β Decay, Other Rare α Decay and β Decay

Dihedral Technology(DHD) Co., Ltd. manufacture and processing/provide multiple specifications and high quality CdWO4 crystal,targets,materials.
