The group is recognized for the mechanical design, installation, and alignment of a complex neutron detection and analyzer system that is an integral, state-of-the-art component of the Multi-Axis Crystal Spectrometer (MACS) located at the NCNR. This system is able to detect neutrons with high efficiency from 20 different scattering channels while simultaneously analyzing the individual neutron energies. This multiplexing capability boosts the data acquisition rate 20-fold, while the low neutron background afforded by the mechanical design significantly enhances the signal-to-noise ratio. The combination of these factors has made MACS the best cold-neutron crystal spectrometer in the world.
