Csi Scintillation Crystal

Our range of CsI Scintillation Crystal is one of the brightest scintillators, which was widely used in radiation detection, high energy physics, safety inspection, geological exploration and so on, its maximum of the broad emission at 550nm, could match well with photodiode, so that make the read-out system simplied dramatically
EPIC growed cesium iodide crystal by using non-vacuum modified bridgman method with super pure 99.999% CsI material, the oxygen scavenger reacted with oxide impurities at high temperature, thus ensure the growing environment without oxygen, which was great helpful for the growth of crystal with high purity, meanwhile, the crystal`s anti-radiation hardness was improved dramatically as well.Most importantly, the application of multi-crucibles in the growth process reduced cost considerably
Our CsI(TI) scintillation crystal has its own intellectual property and already made great contribution to the engineering projects in the national 611 institute, also we have sodium doped cesium iodide scintillator(CsI:Na) in availibility, please contact us for further details
