Forging the Future: A Collaborative Path to a Pulsed Power Next-Generation High-Energy-Density Science Facility through a Public/Private Partnership Program*

In an ever-changing geo-political climate, maintaining and strengthening nuclear deterrence remains a critical priority for our nation. However, achieving this objective without conducting underground testing presents a significant challenge. To address this, the U.S. requires capabilities beyond what it currently possesses, particularly in the field of high-energy-density science. A much-needed capability gap in the area of high-energy-density science is a facility that can enable high-yield fusion (>200 MJ). While laser-based technologies have made significant strides and demonstrated a historical ignition record yield of 5.2 MJ, significantly more drive energy is estimated to be needed to achieve high-yield fusion. A potential cost-effective alternative toward this goal is the construction of a pulsed-power machine larger than the existing Sandia Z-machine. The National Nuclear Security Administration (NNSA) and the national laboratories have been actively exploring options for the execution of such a machine. However, the current budget climate poses a significant hurdle in terms of affordability. To overcome this challenge, one potential approach is to pursue a cost-shared public/private partnership, leveraging resources and expertise to reduce costs and expedite facility construction. In this presentation, we will discuss options and provide an update on the progress made in developing a path towards a next-generation high-energy density science facility through a public/private partnership program.
