FAQ — LaBr₃:Ce Single Crystal Scintillator
Does LaBr₃:Ce glow visibly under X-rays or gamma rays?
LaBr₃:Ce scintillates under ionizing radiation, but visible brightness depends on radiation intensity and viewing conditions. For reliable detection and spectroscopy, use a PMT or SiPM with appropriate electronics.
Is LaBr₃:Ce hygroscopic?
Yes. LaBr₃:Ce is hygroscopic and is typically supplied in an encapsulated package to protect it from moisture. Do not open the encapsulation.
Can I use LaBr₃:Ce with a SiPM?
Yes. LaBr₃:Ce can be coupled to SiPMs for compact gamma detectors. Good optical coupling (no air gaps) and stable bias/readout electronics help achieve the best performance.
What is LaBr₃:Ce commonly used for?
LaBr₃:Ce is widely used for gamma-ray spectroscopy, isotope identification, radiation monitoring, and research instrumentation where high resolution and fast response are important.
Do I need a PMT or SiPM to use this scintillator?
For quantitative measurement (spectroscopy), yes. The scintillator converts radiation into light, and a PMT/SiPM converts that light into an electrical signal for processing by an MCA or digital spectrometer.
How should I store and handle LaBr₃:Ce crystals?
Keep the crystal encapsulated, store in a dry environment, and avoid high humidity or condensation. Do not scratch the window; keep optical surfaces clean for best coupling.
What sizes and configurations are available?
Common configurations include 1″, 1.5″, and 2″ encapsulated crystals (custom sizes/housings may be available). Contact us with your target size, window type, and readout method (PMT or SiPM).
Do you provide crystal-only or complete detector assemblies?
We can supply encapsulated crystals and may support detector integration (PMT/SiPM coupling) depending on your project. Share your requirements and we’ll recommend a configuration.
Why choose LaBr₃:Ce vs NaI(Tl)?
LaBr₃:Ce typically offers better energy resolution and faster response than NaI(Tl), which can improve peak separation for spectroscopy (system performance depends on size, coupling, and electronics).
Does LaBr₃:Ce support neutron/gamma pulse-shape discrimination (PSD)?
LaBr₃:Ce is primarily a gamma scintillator. If you need PSD for neutron/gamma discrimination, materials like CLYC are commonly used.
