DOE seeks proposals for AI data centers at Paducah
The Department of Energy’s Office of Environmental Management has issued a request for offer (RFO) seeking proposals from U.S. companies to build and power AI data centers on the DOE’s Paducah Site in Kentucky. Companies are being sought to potentially enter into one or more long-term leasing agreements at the site that would be solely funded by the applicants.

In the GAMMA 10 tandem mirror, neutral hydrogen densities in the central-cell and anchor-cell have been estimated by measuring spatial profiles of H line-emission with absolutely calibrated H line-emission detectors. Absolute measurements of H line-emission enable us to evaluate the neutral density based on the collisional-radiative model. Recently, single channel H line-emission detectors were installed in plug/barrier cells, where the axial confining potentials are produced by electron cyclotron resonance heating. We studied the neutral particle behavior in the plug/barrier cells for the first time using the newly installed H line-emission detectors. Moreover we have designed and installed a multi-channel H line-emission detector system to study the neutral hydrogen behavior in the plug/barrier cell.
