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.
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.

A detailed study on the capacitively coupled radio-frequency (CCRF) argon discharge with metastable atom density and the effect pressure has been undertaken. Specifically, dielectric layers of borosilicate glass and alumina were introduced to the discharge to examine their influence on the discharge characteristics and to study the properties of the plasma. A model for the argon plasma based on the three moments of the Boltzmann equation together with the Poisson equation was used. The properties of the argon plasma presented are based on the averaged cycle, especially the electron temperature, the electric potential, and the metastable atom density. The electron temperature and the metastable atom density decreased in the presence of the dielectric layers, whereas the electric potential had a high value. Sensitivity analysis showed that the surface charge concentrations on the borosilicate glass and alumina dielectrics and the gap voltage increased with the increase of the relative permittivity; the plasma parameters also increased with increasing gap voltage.
