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.”

The report presents the recent results of experiments with deuterium neutral beam injection in the Gas Dynamic Trap (GDT) device. The experiments were to demonstrate the peaking up of the DD reaction near the fast ion turning points that represents the essential feature of the GDT-based neutron source (GDT-NS). The critical assumption for feasibility of GDT-NS is that the fast ion relaxation in the warm target plasma is to be determined by two-body Coulomb collisions without considerable increase of the scattering rate caused by instabilities, otherwise the neutron flux peaks may strongly flatten out. The comparison of the measured axial profile of the DD reaction intensity with simulation results allows to validate this assumption for the plasma parameters of GDT device
