Gamma detector Cesium iodide Scintillation Crystal
Gamma detector Cesium iodide Scintillation Crystal
Cesium Iodide - CsI scintillator crystals have the following issues which should be noted. They are:
Relatively poor emitters - emitting 4,000 photons/MeV (5% of NaI(Tl))
Are slightly hygroscopic
Properties:
| Density(g/cm3) | 4.51 |
| Melting Point (K) | 894 |
| Thermal Expansion Coefficient (K-1) | 54 x 10-6 |
| Cleavage Plane | None |
| Hardness (Mho) | 2 |
| Hygroscopic | Slightly |
| Wavelength of Emission Maximum (nm) | 550 |
| Lower Wavelength Cutoff(nm) | 320 |
| Refractive Index at Emission Maximum | 1.79 |
| Primary Decay Time (ns) | 1000 |
| Afterglow (after 30ms) [%] | 0.5 – 0.8 |
| Light Yield (photons/keV) | 52- 56 |
| Photoelectron Yield [% of NaI(Tl)] (for γ-rays) | 45 |
Advantage:
Well matched with PD
Good stopping power
Good energy resolution/ low afterglow
Application:
Gamma detector
X-ray imaging
Security inspection
High energy physics
