The rf buncher is a compact cavity having magnetic alloy (MA) cores and operates in the wide frequency range between 18 and 45 MHz without any tuning systems. Bunched beams of H+, O5+, and Ar8+ ions have been produced successfully and measured using a newly designed Faraday cup with good time resolution. In this paper, the design of the MA-loaded buncher cavity and the results of the beam test are presented. A detailed description of the HiECR beam transport line and the design of the new Faraday cup are also given.}, pages = {4227--4231}, title = {Broadband Buncher Cavity for Beam Transport Line of HiECR Ion Source}, volume = {45}, year = {2006} }
