N2 - We report on the observation of intense pulses of sulphur negative ions extracted from a Cs-beam sputter source and produced by the impact of 532 nm photon pulses from a Nd-YAG laser on a FeS cathode. Peak currents of about 3 mA are obtained after extraction and preacceleration of the negative ions, which are subsequently analyzed by accelerator mass spectrometry. The time structure of the 32S- negative ion current is measured and shows a complex behavior not yet fully understood.
