Department of Energy Under Secretary for Science and Genesis Mission lead Darío Gil participated in a session at the Nvidia GPU Technology Conference on March 17 that coincided with the announcement of the DOE’s $293 million Genesis Mission request for applications, which invites interdisciplinary teams to submit ideas for projects addressing over 20 of Genesis’s stated national challenges, several of which focus on accelerating nuclear research and nuclear energy output.
“We seek breakthrough ideas and novel collaborations leveraging the scientific prowess of our national laboratories, the private sector, universities, and science philanthropies,” said Gil.

The energy spectra of fast neutrons backscattered from aluminum, iron, lead, and Perspex were measured for primary neutron energies of 0.5, 1.0, 1.5, and 1.8 MeV. The energy spectra were obtained as a function of the thickness of the scattering material up to two mean-free-paths. The experimental results are compared with Monte Carlo calculated values.
