Abstract :
As a part of a code validation study, we have compared radiographic simulations generated using the HADES code against experimental measurements of a set of common materials of known composition and density: graphite, Teflon, Delrin, magnesium, silicon, titanium, and water cylinders. HADES calculations show good agreement with radiograph measurements. Discrepancies between simulation and experimental data are analyzed. Sources of error and future model improvement are discussed.
