CsI (Cesium Iodide) Crystal Scintillators for Nuclear Spectroscopy

Cesium iodide (CsI) crystal scintillators provide reliable performance in gamma-ray detection and nuclear spectroscopy applications. Available in a wide range of sizes, shapes, and form factors, these scintillators support both single-detector and array-based configurations.

Key Properties of CsI Crystal Scintillators
  • Mechanical Durability: Resistant to cleavage and cracking under mechanical stress, making it suitable for portable and field-deployed instruments.
  • Low Hygroscopicity: Minimally sensitive to moisture compared to many other halide scintillators, simplifying handling and encapsulation.
  • Bright Emission & Spectral Match: Peak emission above 500 nm, well-suited for readout with silicon-based photodetectors such as silicon photomultipliers (SiPM) or photodiodes.
  • Good Resolution & Efficiency: Delivers consistent energy resolution for gamma spectroscopy across a broad energy range.

CsI crystal scintillators are offered encapsulated for protection, integrally coupled to light sensors (PMT, SiPM, or photodiode), or as complete detector assemblies with front-end electronics.
