Rugged CaF2(Eu) Scintillators for Vacuum & Liquid Radiogens
ATR Crystal precision-manufactures Europium-doped Calcium Fluoride (CaF2:Eu), an exceptionally durable scintillation material. Engineered with superior mechanical and thermal shock resistance, it guarantees highly reliable detection across both standard atmospheric conditions and demanding vacuum environments.
- Direct Liquid Contact: Strictly insoluble in water and most organics, allowing safe, direct immersion in liquid radiogens.
- Maximum Efficiency: A perfectly matched refractive index to standard PMT windows and optical couplings ensures optimized light collection.
- Custom Configurations: Highly machinable, supplying custom-specified CaF2(Eu) crystals tailored exactly to your equipment’s dimensional requirements.
