Key Applications
- Radio-Isotope Identification (RIID): Used in handheld devices to identify isotopes and detect shielded neutrons simultaneously.
- Border & Homeland Security: Efficiently detects Special Nuclear Material (SNM) in cargo and baggage screening.
- Oil & Gas Exploration: High-temperature stability and dual-mode detection for advanced well-logging tools.
- Research & Spectroscopy: High-resolution gamma-ray spectroscopy in laboratory environments.
Pulse Shape Discrimination (PSD) Excellence
CLLB utilizes the difference in scintillation decay times between gamma and neutron interactions. This allows for a high , Figure of Merit (FOM), ensuring that gamma-ray backgrounds do not interfere with neutron counts—a critical requirement for He3 tube replacement.
