| Neutron imaging is a powerful diagnostic technique that proved instrumental in the iterative design and improvement of fusion yield on the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. The heart of the neutron imaging instrument is the high-aspect-ratio pinhole array, which in efforts to replicate the performance of a traditional camera obscura for penetrating neutron radiation, requires extreme precision in fabrication, metrology and alignment. This INFUSE project supports researchers from LLNL in the design and fabrication of advanced neutron imaging apertures based on the coded aperture approach for Pacific Fusion’s Demonstration Facility. The coded aperture approach generalizes and relaxes constraints in traditional thick-pinhole imaging, allowing greater freedom in optimization of throughput, resolution, and array fabrication requirements. The contribution of advanced neutron imaging aperture design and fabrication will greatly strengthen PF’s ability to iteratively improve fusion performance on the new facility. |
