A PZT element was studied by bombarding silver particles in the mass range from 1 to 100 pg, and the velocity from 2 to 6 km/s. Output signals were uniquely identified on impact. They were processed on Fourier analysis. We found a simple selection rule using a relationship between Fourier components to discriminate junk events. By using the selection rule, we picked up events, by which a linear relationship between impact energy and output amplitude of the element was established It was found that incident energies above 100 nJ were determined uniquely by a single PZT element.
