| Abstract | Abstract | ||
| <blockquote> | <blockquote> | ||
| - | Add abstract | + | Los Alamos National Laboratory is famous for designing the atomic bombs used at the end of World War |
| + | II in 1945. Post-war, many further advancements were made in the development of nuclear weapons, | ||
| + | and treaty verification also became an important pillar in the lab’s mission. In this talk, I’ll discuss the | ||
| + | evolution of LANL’s work through the decades on space-based nuclear explosion detection. | ||
| + | In addition, x-ray radiography is employed at LANL for both dynamic and static imaging. Knowledge of | ||
| + | the x-ray energy spectrum produced by both flash and continuous sources aids in reconstructing the | ||
| + | density of the probed objects and in assessing machine performance. Compton spectrometers are one | ||
| + | option for conducting spectral measurements. In this technique, x-rays impinge on a converter foil from | ||
| + | which Compton electrons are ejected. The electrons enter the magnetic field region of the spectrometer, | ||
| + | and the electron momentum is proportional to position on the focal plane. From the electron signal, the | ||
| + | x-ray energy spectrum can be determined. Several continuous and flash x-ray sources have been | ||
| + | measured, and a sample of these results will be presented. | ||
