Abstract
A 14 GHz electron-cyclotron-resonance ion source has been designed and built in the last two years. According to computer simulations two so lenoids and a sextupole magnet, made of NdFeB, form a minimum-B-struct ure with an axial magnetic mirror ratio of 2.5 and a maximum radial fi eld inside the plasma chamber of 1.2 T. A 14 GHz microwave system supp lies up to 2.2 kW of microwave power to the plasma. The extracted ion beam was simulated and the extraction lens system was optimized. The e xtracted ions are charge-to-mass analyzed by a 45 degrees bending magn et and the ion currents are measured in a Faraday cup. First charge st ate distributions and ion currents of various elements are presented.
