FRAM v.5: Simple Is Good

The Fixed-Energy Response-Function Analysis with Multiple Efficiency (FRAM) software has been developed and is continuing to be refined at Los Alamos National Laboratory for gamma-ray spectrometry measurements of the isotopic composition of plutonium, uranium, and other actinides. The FRAM v.4 code was released in 2002. Since then, we have added many new features to improve the analysis for better analytical results and to meet user needs. “Simple is good” is the motto of this upgraded version, v.5. We have strived to make this new version as simple and intuitive as possible so that almost anyone can use it effectively without extensive training. Even with a simple user interface, FRAM v.5 retains virtually all the capability of FRAM v.4 and has many new functions for experts to use in addressing the many difficult-to- analyze spectra.
