Lawrence Livermore National Laboratory

Vision: Expand the NCI competencies and technologies to
address NDC problems both at LLNL and partner institutions

Quantitative NDC for Additive Manufacturing (AM)

  • NDC is required to characterize inaccessible surfaces, and density and composition variations; determine physical properties: geometry, density, elemental & molecular composition, thermal, structural, mechanical, stress state, radioactive assay, etc., in all three dimensions and as a function of time
  • Employ acoustic feedback during the AM process

More Quantitative NDC by Multi-spectral and Multi-modal Methods

  • Expand the spectral range of NDC imaging technologies and increase the synergism between different technologies/methodologies
  • For example, using high spatial and energy resolution, spectroscopic detector arrays
  • Couple multi-energy CT with the SIRZ algorithm

NDC for Chip Assurance

  • X-ray CT for verification of integrated circuits with synchrotron or laboratory sources
  • Faster chip assurance
  • Investigate techniques such as limited-view CT and ptychography

Additional NCI Goals

  • As-built modeling — unite diverse and non-coupled technologies such as design and modeling, materials development, characterization and testing, process monitoring and control, reverse engineering, and reuse and waste management into a global package of integration and iteration
  • Portability and speed — reduce the size of new NDC systems to that of a small suitcase while also decreasing the inspection time
  • Faster 3D imaging of dynamic events
  • Fused neutron and x-ray CT algorithms
  • Faster more accurate models
  • Partner with government, academia, labs, and industry
