Deep geologic repository progress—2025 Update
Editor's note: This article has was originally published in November 2023. It has been updated with new information as of June 2025.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.

There is a known demand for a fusion prototypic neutron source capable of emulating the neutron-induced damage caused by fusion. If no such source is developed in a timely and economical manner, the use of fusion as a source of energy will be hindered by material selection and qualification. Presented here is one possible path toward the development of a fusion prototypic neutron source by enhancing an operational neutron generator platform with so-called plasma windows. The use of plasma windows addresses a weakness in the current design by improving the pressure differential between acceleration and the target regions. This improvement, combined with the use of multiple beamlines, represents the possibility of dramatically increasing the fusion neutron flux capabilities of such a system.
