【摘要】 <正>In this work, highly charged ions have been extracted from the advanced Electron Beam Ion Source（EBIS-A）developed in a scientific cooperation between the Dresden University of Technology and the DREEBIT GmbH Dresden.The charge state distributions of ions extracted from the EBIS-A are measured in the pulse and leaky modes under different operation conditions. Ar16+ions with current of 2pA are produced and extracted in the leaky mode. 3×105 Ar18+ions per pulse are extracted in the pulse mode.The ion charge state distribution is a function of the ionization time.
