A single-gap multi-harmonic buncher, developed in collaboration with Argonne National Laboratory, has been installed in the pre-acceleration region of NSC Pelletron. This buncher is required for injecting bunched beam into the booster LINAC, presently under construction. A saw-tooth voltage generated across a single gap formed by a closely spaced pair of grids is used for bunching the dc ion beam produced by the Pelletron accelerator. This saw-tooth voltage is produced by adding a sinewave with its three higher harmonics in proper phase and amplitude. {sup 28}Si beam has been bunched successfully using this buncher. The best FWHM of the bunched beam was 1.5ns and the maximum efficiency of bunching was 50{percent}. The bunching voltage had no steering effect on the beam. {copyright} {ital 1999 American Institute of Physics.}
