Abstract
Medium-resolution gamma-ray spectrometer detectors such as the LaBr3 and CZT detectors present a more practical and less expensive alternative to high-resolution gamma-ray spectrometers because they operate at room temperature, are more compact and reliable, and are easy to use and maintain. Making them capable of isotopic analysis of uranium and plutonium samples is a desirable feature, which is useful in various safeguards applications. The upgraded Fixed-Energy Response-Function Analysis with Multiple Efficiency (FRAM) code can analyze the isotopic compositions of uranium and plutonium from spectra obtained by a LaBr3 or CZT detector system. This upgraded code is FRAM version 6, to be released soon. It is a major upgrade from the current version 5.2, which was released in 2013. In addition to the capability to analyze the LaBr3 and CZT spectra, FRAM v.6 will implement various new features to improve usability, sustainability, compatibility, and maintainability.
