摘要
A tandem microwave-driven plasma source for the production of H- ions has been developed and tested. The source has a microwave-driven primary chamber with a thermionic cathode-driven secondary plasma. This source was used to experimentally verify certain aspects of a theoretical model of H- production by Hiskes. A general agreement with the theory was found for the dependence of produced H- current with the plasma electron temperature. In addition, it appears that a surface production mechanism on the BaO-impregnated cathode enhanced the H- current production. Experimental results are given and compared to present theoretical understanding.
