Description
BaF2 Scintillation Crystal is commonly used as a UV-IR window material. Its broad transmission spectrum runs 190 to 1200 nm. High transmittance, slight hygroscopicity, and a refractive index with little temperature dependence define it. High energy and time resolutions let it measure energy and time spectra simultaneously. The 0.6 ns fast component enables sub-nanosecond timing. The material is barium fluoride.
BaF2 Scintillation Crystal specifications
Crystal system: cubic. Density: 4.89 g/cm³. Radiation length: 2.03 cm. Melting point: 1280°C. Hardness: 3 Mohs. Decay constant: 0.6-620 ns. Peak emission: 220-310 nm. Light yield: 10,400 photons/MeV. The 220-310 nm emission matches common PMTs. The short radiation length keeps detectors compact.
BaF2 Scintillation Crystal in radiation fields
Excellent radiation hardness reaches 10^6 rad or more. High-energy physics detectors run it for years. Simultaneous energy and time measurement cuts channel count. Coincidence systems get cleaner triggers. The fast component suits time-of-flight PET research and coincidence detection.
Typical applications
High energy physics. Nuclear physics. Nuclear medicine. Beam-loss monitors use it for fast response. Nuclear medicine benefits from the fast timing. Reactor monitoring exploits the radiation hardness. For the window version, see our BaF2 Infrared Crystal.
