Microcalorimetry and Nuclear Data (MiND) Workshop

ORAL

Abstract

The U.S. Department of Energy Office of International Nuclear Safeguards hosted a workshop on microcalorimetry and nuclear data (MiND) in June 2023. The MiND workshop included participants from all these fields, with the main objective of identifying a roadmap for priority nuclear data, stakeholders, partnerships, and opportunities.



High resolution microcalorimeters can resolve low energy γ-rays, X-ray and α-particle with ultra-high energy resolution, allowing non-destructive analysis of isotopic compositions and dramatically improving nuclear decay data. Microcalorimeters can also measure eV level conversion electrons and nuclear recoil, with the former well-suited for in-beam measurements of actinide cross sections and the latter providing insight into lattice displacement processes for space and fusion applications. Microcalorimeters can provide a better understanding of the age of the earth and the solar system, improve post-detonation forensics measurements and significantly reduce sample analysis turn-around time for safeguards applications.



In this talk, we will summarize the workshop and path forward. This work has been supported by the US DOE under contracts DE-AC02-05CH11231 (LBNL), 89233218CNA000001 (LANL) and DE-AC52-07NA27344 (LLNL) and approved for release by LANL (LA-UR-23-27092) and LLNL (LLNL-ABS-851298).
