Product description

Cerium bromide (CeBr3) crystals are excellent scintillation crystals with a density of 5.1g/cm3, resulting in 56,000photons/MeV (1.3 times NaI) for an energy resolution of 4.5% with a attenuation time of 17ns for 662keV. This material is easy to hygroscopy, must be encapsulated before it can be used. Cerium bromide crystal has a slightly lower energy resolution than lanthanum bromide crystal, but this kind of crystal has no natural background or very low natural background, which can be used in petroleum logging and other situations requiring high background and high energy resolution.
At present, we can batch grow lanthanum bromide crystals of 1 ", 1.5 "and 3" diameter in common sizes, and also can batch customize crystal materials of unusual sizes according to customer needs.
