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.”

An experiment of Alfvén wave excitation and heating of a field-reversed configuration (FRC) plasma is presented. A low frequency magnetic pulse is applied to the FRC plasma by an azimuthally symmetrical antenna. After the pulse applied, an obvious increase of the plasma energy and the propagation of the magnetic wave are simultaneously observed. The excited wave propagates along the steady magnetic field line with the radially distributed phase velocity. The phase velocity outside the separatrix agrees the dispersion relation of the shear Alfvén wave. On the other hand, it is close to the acoustic speed, inside the separatrix. It is also observed that there is a generation of a non-oscillating toroidal magnetic field, which is possible to cause the heating of the FRC plasma.
