Model CEBRS-2x2 Cerium Bromide Scintillation Detector is a high-efficiency scintillation detector featuring a 2 x 2 in. CeBr3 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 Mirion proprietary connector. CeBr3 detectors have a proven record of long term reliability and stability. 

The CEBRS-2x2 CeBr3 detector is LED temperature-stabilized*, eliminating the peak-shift problems inherent in scintillation detectors. This makes the CEBRS-2x2 detector suitable for use in non-air-conditioned rooms as well as in field applications. The LED temperature-stabilized probe continuously monitors and adjusts the gain of the detector to ensure consistent performance throughout the entire temperature range. The consistent performance allows users to perform nuclear identification under all typical indoor and outdoor conditions while maintaining the highest confidence in the results obtained by the instrument. 

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

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 unit – the Mirion all-in-one HVPS, preamplifier, and digital MCA – the CEBRS-2x2 detector 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.
