YAG(Ce) Scintillator (YAG(Ce) Scintillation Crystal)
Cerium-doped yttrium aluminum garnet (YAG:Ce) is a high-performance inorganic scintillation crystal with excellent physical and scintillation properties. It features a fast decay time of ~70 ns, high light yield of ~18,000 photons per MeV, and a prominent emission peak at 550 nm that matches well with silicon photodiodes. Boasting outstanding radiation hardness, good thermal stability and non-hygroscopicity, it can work stably in harsh extreme environments. It is widely applied in radiotherapy dose distribution detection, high-resolution X-ray imaging and high-energy particle monitoring.
OST Photonics can supply high-quality YAG:Ce crystals and customized YAG:Ce scintillation screens, with a full range of design options tailored to meet the diverse application requirements of our customers.
Application
High-resolution X-ray and electron microscopy imaging screens
Beam profile monitoring for free electron lasers and particle accelerators
Clinical linear accelerator real-time X-ray radiation detection
Light charged particle detection with photodiode readout systems
Features
Fast scintillation decay time
Emission peak at ~550 nm, perfectly matching the sensitivity of silicon photodiodes
Excellent mechanical/chemical stability, non-hygroscopic and high temperature resistant
Good radiation hardness for long-term operation in high-radiation environments
Flexible fabrication can produce ultra-thin screens down to 0.005 mm thickness
Production and Supply Capability
- Maximum Size: ɸ80mm x 200mm
- Available items: monolithic crystal, scintillation screen, transparent ceramics
Scintillation Screen Design Options of YAG(Ce) Scintillators
- Freestanding ultra-thin scintillation screen.
- Ultra-thin scintillation screens can be coupled to a substrate with optical adhesives in order to achieve better optical readout.
- Scintillation screens can be inserted into frames(Aluminum, Stainless steel) for easier manipulation.
- We can provide customized markings such as a grid, cross, or scale on the surface of the screen for easier beam visualization.
- We can provide various coating on the surface of the screen upon request, such as reflection coatings(Al, Au, Ag, etc.), AR coating, diffusion painting(TiO2, Al2O3), and conductive coatings(Al, ITO, C).
