Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

WHAM: Realta gets first plasma with 17 Tesla magnets in mirror fusion test
The magnetic mirror fusion concept dates to the early 1950s, but decades ago it was sidelined by technical difficulties and researchers turned to tokamak fusion in their quest for confinement. Now it’s getting another look—with significantly more powerful technology—through WHAM, the Wisconsin HTS Axisymmetric Mirror, an experiment in partnership between startup Realta Fusion and the University of Wisconsin–Madison.

The neutron-induced gamma-ray production cross section for the first excited state of l4N was measured for neutron energies from 2.65 to 3.55 MeV at intervals of 100 keV. An angular distribution from 45 to 135 deg in 10-deg steps was measured at an incident neutron energy of 3.45 MeV. Neutrons were produced by the 7Li(p,n)7Be reaction using a pulsed proton beam from the University of Massachusetts Lowell 5.5-MV Van de Graaff accelerator. The interaction of neutrons from the 7Li(p,n)7Be* reaction in the sample was taken into account. A calibrated 235U fission chamber was used to measure the absolute incident neutron fluence. Gamma rays were detected by a Ge(Li) crystal surrounded by a NaI(Tl) anti-Compton annulus. This spectrometer was used in conjunction with the pulsed-beam time-of-flight technique to attenuate background. The measured cross section compares favorably with other experimental data and with the ENDF/B-VI evaluation.
