ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

The National Ignition Tuning Campaign involves a dozen capsule designs. These capsule designs vary in diameters, layer thicknesses, and germanium doping levels, examining implosion velocity, entropy, hot-spot shape, mix, and uncertainty. Overall yield of these tuning capsules involves meeting all individual specifications, including layer thicknesses, doping levels, outer surface smoothness, and inner diameter. The yield of scaled tuning capsules with acceptable inner diameters is greatly affected by the available mandrel diameter and its size distribution.Surface low mode and isolated defect specifications have been tightened. The new specification allows smaller and fewer isolated defects. The surface specification is quantified in terms of low mode factors, peak velocity root-mean-square (PVRMS), mix mass, and ignition threshold function (ITF). The total mix mass from all isolated defects should be <40 ng, and the PVRMS value should be <10 m. While most current capsules meet the PVRMS requirement, only some tuning capsules have a mix mass <40 ng. The majority of capsules have a mix mass >40 ng, caused by a few larger domes. The ITF is related to isolated defects and capsule power spectra. Some capsules exceed the ITF specification value of 1.3.
