CeBr3 Crystal,25x25mm,CeBr3 Scintillator, Cerium Bromide,1"x1"

Cerium Bromide (CeBr₃) scintillation crystals are grown using the Bridgman technique at Epic Crystal. The current maximum crystal ingot size reaches approximately 100 mm in diameter and 150 mm in length, enabling the production of high-performance detectors for demanding radiation detection applications.

Available configurations include:

• Encapsulated crystals (standard and ruggedized versions)
• Complete detector assemblies coupled with photodetectors such as PMTs or SiPMs

Outstanding Scintillation Performance

CeBr₃ is renowned for its superior scintillation properties, making it ideal for high-resolution gamma-ray
spectroscopy and real-time radiation monitoring. Key performance characteristics include:

• High light output – comparable to NaI(Tl), ensuring strong signal generation
• Fast decay time (~17 ns) – supports high count rates and excellent timing resolution
• Superior energy resolution (typically <4% at 662 keV) – enables precise identification and differentiation of gamma-ray energies
• Ultra-low intrinsic radioactivity (<0.005 counts/second/cm³) – minimizes background interference, critical for low-background and homeland security applications
• High effective atomic number (Zₑff ≈ 46) – provides excellent gamma-ray stopping power and detection efficiency

Application Advantages

While CeBr₃ crystals are more costly than conventional scintillators like NaI(Tl), their exceptional energy resolution, low self-activity, and fast response make them a preferred choice for applications requiring high fidelity and accuracy in radiation detection, including:

• Nuclear safeguards and non-proliferation
• Environmental radiation monitoring
• Oil & gas well logging (with ruggedized packaging)
• Radioisotope identification (RIID)
• Scientific research and spectroscopy

Hermetic encapsulation in aluminum (standard) or stainless steel/titanium (ruggedized) ensures long-term stability and protection against moisture, preserving optical and mechanical integrity in diverse operating environments.
