Description

Model NAIS-2x2 Sodium Iodide Scintillation Detector is a high-efficiency scintillation detector featuring a 2 x 2 in. NaI(Tl) crystal in a hermetically sealed aluminum housing, including a photomultiplier tube, an internal magnetic/light shield, a high-voltage power supply (HVPS), stabilization electronics, preamplifier, and an 8-pin CANBERRA proprietary connector. NaI(Tl) detectors have a proven record of long term reliability and stability.

The NAIS-2x2 NaI(Tl) detector is LED temperature-stabilized*, eliminating the peak-shift problems inherent to scintillation detectors. This makes the NAIS-2x2 suitable for use in non-air-conditioned rooms as well as in field applications.

The detector comes with a generic mathematical efficiency characterization known from CANBERRA’s line of high-resolution HPGe detectors. Quantitative measurements can be performed without the use of calibration sources using CANBERRA’s mathematical efficiency calibration software ISOCS™/LabSOCS™.

The housing is of an all-metal construction and features a robust locking mechanism for increased reliability. The cam lock provides a positive mechanical connection to the tube base instead of relying on the electrical pin friction only.

In combination with the Osprey – CANBERRA’s all-in-one HVPS, preamplifier, and digital MCA – the NAIS-2x2 becomes part of a high-performance scintillation spectrometry system suited for a wide range of applications – laboratory (with Model 727 shield), radiation monitoring networks, field use, etc.
