Description
PbWO4 | Lead Tungstate Scintillation Crystal
The PbWO4 Scintillation Crystal (Lead Tungstate) is one of the densest oxide-based scintillators available. Known for its short radiation length and small Molière radius, this crystal is the industry standard for high-precision electromagnetic calorimeters in high-energy physics.
One Crystal, Three Critical Advantages
-
Extreme Density: At $8.28\text{ g/cm}^3$, it provides the highest stopping power for high-energy particles.
-
Radiation Hardness: Retains stable optical transmittance after exposure to gamma radiation up to $10^6$ rad.
-
Compact Design: A short radiation length ($0.89\text{ cm}$) enables maximum detection efficiency in space-constrained environments.
Advanced Detection Technology
Our Lead Tungstate crystals are engineered for stability and precision in the world’s most demanding experimental physics environments:
-
Ultra-Fast Response: Features a rapid decay time, minimizing dead time in high-rate counting applications.
-
Optimized Light Output: Scintillation peaks between 440–550 nm, perfectly matching SiPM and PMT sensitivity.
-
Stable Properties: Non-hygroscopic and chemically stable for long-term reliability in the field or lab.
