Sodium doped Cesium Iodide or CsI(Na) has a wavelength of emission peak at 420nm, which makes it well matched to the photo-cathode sensitivity of bialkali photo multiplier (PMT), CsI(Na) scintilaltion crystals also has a high light output yielding up to 85% of NaI(Tl). Compared to NaI(Tl), it is a relatively soft and plastic material without cleavage plane, which makes the CsI(Na) scintillator materials suitable for harsh environmental applications, like well-logging, space research ect..
Hangzhou Shalom EO offers the CsI(Na) custom sctintillator, the polished and encapsulated CsI(Na) crystals is available, and the Photo Multiplier (PMT) could be installed if it is requested.
