CsI(Na) Scintillation Crystal Description:
CsI(Na) Scintillation Crystal is a new type of scintillation crystal material. CsI(Na) Scintillation Crystal is similar to NaI(TI) crystals. Its emission spectrum peaked at which matches with PMT. It is not sensitive to temperature; therefore it can be a good choice when using in high temperature and OutSpace environment.
Cesium Iodide, activated with Sodium - CsI(Na) - is one of the brightest available scintillators, with a broad emission peaking at 420nm. CsI(Na) has good stopping power, physically rugged and well suited to a broad range of applications.
CsI(Na) Scintillation Crystal Advantages:
- Relatively bright
- Good absorbers with good stopping powers
- Broadly emitting with a 420nm peak, well-matched to use with PMTs
- Robust with good mechanically characteristics
