Abstract

Acoustic waves induced by an intensity-modulated focused ion beam (FIB) have been measured. The experiments were performed with Ga+ ions of 35 keV at a current of 3 nA and variable chopping frequency up to 10 MHz. The acoustic signals were detected by means of a piezoelectric sensor with integrated pre-amplifier. In the paper the experimental setup and the results of first measurements are presented. Evidence for FIB induced acoustic waves has been found.
