Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

We have developed a numerical raytrace model, SHELL3D, which simulates the backlit imaging of cryogenic inertial-confinement fusion (ICF) ignition capsules in three dimensions. We have used this model to investigate the limitations of backlit shadowgraphy as a diagnostic of hydrogen ice surface quality inside the capsules. We impose known modal perturbations upon the simulated inner ice surface, and produce simulated shadowgraphs which are then analyzed as if they were real experimental data. We find that power spectra derived from backlit shadowgraphs appear to be reliable indicators of ice surface power spectra out to Fourier mode numbers as high as 80. We also suggest that some advantages may be obtained by using a collimated backlight, and possibly by utilizing backlit transmission interferometry. These results support the conclusion that backlit shadowgraphy is a valid quantitative diagnostic of lower-mode ice surface imperfections inside transparent spherical ICF shells.
