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.”

In this paper, multi-electron interactions for low-charge-state ions in heavy ion beam fusions (HIBF) is studied through exploring theoretical approaches and developing improved models. An improved classic trajectory Monte Carlo model and corresponding codes have been built to implement those simulations, mainly though the intensive computations in solving many-body Hamiltonian Equations. Following the results present in the previous meetings (Ref. 1-2), the results here for the low-charge-state ions of Xe, Bi and other ions colliding with noble gas are provided, and show that multi-electron effects are obvious and their cross section can reach about 40% of the total cross section. The improved code employs parallel computing, and is expected to be an integral part of a plasma simulation package to study the atomic effects in plasma beam transportation and focusing in HIBF, and help to provide improved physical insight into current HIBF experiments and future studies.
