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.

General Kenneth Nichols and the Manhattan Project
Nichols
The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.
As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

Controlling the transport in the plasma edge of high temperature plasmas has recently been extended by a sophisticated option - the stochastization of the magnetic cage confining the plasma. The idea is to induce a chaotic magnetic field structure in the edge which can act as a magnetic valve to control heat and particle fluxes between the confined plasma and the plasma facing components. This tool is applied in both, stellarators as well as tokamaks. In this lecture an introduction into the topic will be given. The topics are (a) generation and structure of chaotic magnetic edge layers, (b) plasma transport with stochastic magnetic fields including the resulting three-dimensional plasma wall interaction and (c) impact of a plasma response. However, this field is matter of intense ongoing research and hence this lecture gives a systematic introduction into the challenges based on examples from the TEXTOR tokamak.
