Scintillation counter - NAIS-2x2
Model NAIS-2x2 Sodium Iodide Scintillation Detector is a high-efficiency scintillation detector featuring a 2 x 2 in. NaI(Tl) crystal in an 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 LED temperature-stabilized probes continuously monitors and adjusts the gain of the detector automatically to ensure consistent performance throughout the entire temperature range. The consistent performance allows users to perform nuclear identifications under all conditions and environments that are typically encountered indoor and outdoor, while maintaining the highest confidence in the results obtained by the instrument.
