SiPM-Based Alpha/Beta Scintillation Detectors
These thin SiPM-based scintillation detectors are designed for simultaneous alpha and beta radiation detection. They incorporate a silicon photomultiplier (SiPM) readout, integrated temperature-compensated bias generator, and low-noise preamplifier in a compact assembly.
Key Features of SiPM Alpha/Beta Detectors
- Thin Profile Design — Low-profile construction suits portable instruments, surface contamination monitors, and space-constrained setups.
- Integrated Electronics — Built-in temperature-compensated SiPM bias supply and preamplifier simplify system integration and reduce external component needs.
- Alpha/Beta Discrimination — Effective separation of alpha and beta events through pulse height or shape analysis, depending on scintillator selection.
- SiPM Readout Advantages — Compact size, low-voltage operation, magnetic field immunity, and solid-state reliability compared to traditional PMT-based detectors.
Configurations are available with thin plastic scintillators or specialized coatings optimized for alpha/beta response. The design supports easy integration into handheld probes, fixed monitors, or automated counting systems.
