Coincident gamma ray detection system, Scintillation Detector,

The National Institute of Standards and Technology (NIST) is seeking information from sources that may be capable of providing a solution for a coincident gamma ray detection system. The system consists of two scintillation detectors, one for gamma rays and the other for combined neutron/gamma, along with their associated photomultiplier tubes. The detectors will be used in a neutron/gamma field generated by a portable neutron generator for quantitative elemental determination in semiconductor bulk material. Some key points to consider: • The system should be able to minimize background gamma rays for an improved signal-to-noise ratio and enhanced detection limit for critical elements in semiconductor material. • The proposed portable neutron generator-based prompt gamma activation analysis (PGAA) should be suitable for elements with high capture cross-sections. • Companies responding to this notice should provide information about their equipment, including technical specifications, performance capabilities, and any customization options. • Respondents should also indicate whether their equipment is manufactured in the United States and provide details about any plans for changes in manufacturing location.
