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 full-energy peak (photopeak) efficiency and peak-to-total ratio of a closed-end coaxial high-purity germanium detector were calculated and compared with the experimental measurements in the energy range between 60 and 1863 keV. The attenuation of photons by the source itself (self-absorption), the source container, and the detector end cap materials is also included. Many experimental readings have been taken for the source-detector system used in this investigation. By comparison, the calculated and experimental full-energy peak efficiency and peak-to-total ratio values are in good agreement; the overall percentage error is <3%.
