Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.”

ANKA is a ramped 2.5-GeV electron synchrotron light source, which can be operated at all energies from 500 MeV to 2.5 GeV. An online area monitoring network makes it possible to measure the radiation from the decaying beam at eight stations every minute. It consists of two stationary and six mobile stations with a gamma and a neutron detector, which are connected with a central computer by a bus system. Measuring devices and software were developed or customized for ANKA.Special machine shifts were dedicated to the systematic investigation of beam lifetime and ambient equivalent dose, which depend on the beam energy, beam current, and operating conditions of the storage ring.The highest dose rates are measured in the forward direction of insertion devices. The beam is lost at the device with the smallest aperture. Local shielding of the storage ring and operating conditions can be improved with time-resolved dose rate measurements at locations with high dose levels. Low beta optics improves the lifetime of electron beams circulating in vacuum chambers with small aperture. This helps to reduce the dose rate. Furthermore, this has the advantage of reducing the dose rate without the drawback of extra costs for additional shielding.
