Abstract :
NRL scientists have developed an instrument that has extreme sensitivity to energy dissipation in mechanical resonators. It has many potential applications, including detecting and identifying low levels of both chemical impurities and structural defects. While previous instruments measured loss in a resonator to one part in ten, the new instrument measures mechanical loss to one part in 104 or better. Thus, the new spectrometer can separate low level signals from background signals that are several orders of magnitude larger
