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.

We welcome ANS members who have careered in the community to submit their own Nuclear Legacy stories, so that the personal history of nuclear science and technology can be captured. For information on submitting your stories, contact nucnews@ans.org.
I graduated with a mechanical engineering degree from Osmania University in Hyderabad, India, and took up nuclear engineering when I was awarded a scholarship by an organization called His Exalted Highness The Nizam of Hyderabad’s Charitable Trust. That scholarship enabled me to do graduate work at Pennsylvania State University, and I enrolled there in 1966. One of the terms of the scholarship was that I return to India after graduation. Hence, I returned to India in 1972 after receiving my Ph.D. and began working at the Bhabha Atomic Research Centre in Mumbai.

Dielectric mirrors have been considered for both magnetic and inertial confinement systems. Such mirrors are comprised of multiple thin bi-layers of high and low refractive index materials deposited onto a substrate. Three dielectric mirror types were fabricated to reflect at the KrF laser wavelength of 248 nm and these mirrors irradiated at ∼ 175 °C in the dose range of 0.001 to 0.1 x 1025 n/m2 (E>0.1 MeV.) Mirror reflectivity was measured on as-irradiated and on 300 and 400 °C vacuum annealed mirrors. The best performing mirror overall, the alumina/silica multilayer mirror, did not appear to have degraded reflectivity in the as-irradiated or the as-irradiated and annealed conditions. For the highest dose, annealed condition degradation was observed in the hafnia silica mirror. Additionally, laser induced damage threshold was measured on the best performing mirror (the alumina/silica mirror) with a resulting threshold of > 1 J/cm2, For this mirror, the damage threshold was not discernibly degraded by neutron irradiation. These findings are somewhat in contradiction to earlier work, which suggested poor performance of dielectric mirrors at an order of magnitude lower neutron dose. In conclusion, the current findings, while preliminary, suggest the possibility for using dielectric mirrors to much higher dose levels.
