Static and dynamic radiography using high-intensity-laser-based MeV photon sources*

A recent effort led by Los Alamos National Laboratory studied the development of flexible, compact x-ray sources for static tomographic radiography and flash radiography at facilities requiring high brightness dynamic imaging with a goal of developing brilliant x-ray sources with small spot size, short pulse duration, and tunability in dose and spectrum. Results from recent experiments will be presented, evidencing the maturity of this technology for a variety of applications. Also shown will be how dose and spectra can be optimized through use of structured laser targets. Results of a simulation study of laser-target interaction using the VPIC kinetic plasma modeling code and the MCNP transport code will also be reviewed.
