... Tour de force groundbreaking experiments have demonstrated the significant advance of reactor sources for time-resolved elastic and inelastic neutron scattering with atomic resolution on millisecond time scales to measure response to perturbations of materials using timestamped data and a complex sample environment on the Multi-Axis Crystal Spectrometer (MACS)

... manufacturing, neutrons play a distinct role in the measurement of materials properties. They are uncharged and have deep penetration of solids relevant to bulk measurements needed for industry -- for example, they are used to measure the porosity of rock for mining; they measure nondestructively the chemical profile, bulk modulus, and embrittlement of industrial-relevant materials such as cement and steel; and their unique atomic interactions with isotopes are used to map out light elements, including hydrogen placement in soft materials such as polymers and biological systems and drugs, lithium ion batteries, fluid flow in fuel cells, and internal combustion engines.

... Key Conclusion: The reduction of instrument staff, already low by international standards, is reducing capabilities essential for a world-class user facility and reducing NCNR's ability to develop and continuously upgrade cutting-edge instruments, necessary for a very old reactor to increase scientific productivity. Improvements in efficiency and technology developments have reached their limits of maximizing the efforts of the current staff over the past 7 years of flat budgets.

... It is essential for continued success at NCNR that the instrument staff can continue to perform its own research, thus attracting and retaining the best staff and users, and that this program of upgrades and enhancements is supported as a core part of facility operations to meet its mission to the user community.
