Operational Comparison of the ARM SGP AERI and BN AERI Instruments

The U.S. Department of Energy's Atmospheric Radiation Measurement program Southern Great Plain Atmospheric Emitted Radiance Interferometer has been in operation since May 1995. This instrument has collected a vast amount of atmospheric-emitted radiance data during its decade-long operation. In early 2003, the U.S. Department of Energy's Remote Sensing Laboratory operated by Bechtel Nevada acquired a more advanced spectrometer, the BOMEM MR300 Fourier Transform Infrared. The Bechtel Nevada spect… more

End of Enrichment Reconstruction

The age and composition of special nuclear material (SNM) offers a great deal of forensic information; e.g., likely producer or country of origin. Nuclear materials (nuclides) decay at different rates, often in a chain fashion; therefore, the composition of the nuclides changes over time. Trace nuclides in special nuclear material often carry more information regarding age and original composition, but trace nuclides can be easily lost in 'approximations.' Current decay calculation technology i… more
