Description

The 3×3 NaI(Tl) Scintillator Detector is an instrument for precise gamma-ray measurement. It is a sealed detector combining scintillation materials with electronics, with direct-reading electrical pulse output. A sealed construction means stable performance. The crystal plus the PMT arrive in one sealed unit. The 3-inch standard fits common shields. The working principle is the scintillation counter.

NaI(Tl) Scintillator Detector components

Dia. 3×3 inch NaI(Tl) crystal (high light yield, good energy resolution) paired with a Hamamatsu Dia. 3 inch CR119 PMT (8-stage, 14-pin). Stable high-gain performance. Spectra stay sharp over long runs. 8-stage gain keeps signals strong. Matched sizes maximize light collection.

NaI(Tl) Scintillator Detector design

The durable aluminum housing gives physical protection plus EM shielding. The detector outputs scintillation events as electrical pulses. It connects to multichannel analyzers (e.g., Tubular Digital MCA) or DAQ systems. Plug into your MCA and count. Aluminum shields against interference. Integration is straightforward.

Key features

Scintillator material. Hamamatsu CR119 (8-stage, 14-pin). Lightweight durable sealed aluminum housing. Direct electrical pulse output. High gain stability for long-term monitoring.

Typical applications

Environmental sampling. Medical isotope analysis. Laboratory spectroscopy. Industrial field monitoring. The standardized 3-inch form factor fits most lead shielding and collimators. Field teams value the rugged housing. Match the detector to your energy range. Medical labs need the stability. For the crystal alone, see our NaI(Tl) Scintillation Crystal.
