negative ion source volume production vibrationally excited molecules magnetic filter double plasma discharge isotope effect
The production of H^- and D^- ions in a pure volume source has been studied. In our double plasma negative ion source, both energy and density of fast electrons are well controlled. Using this source, enhancement of H^- or D^- production has been achieved. Under the same discharge power, the extracted H^- or D^- current in the double plasma operation is higher than that in the single plasma operation. At the same time, measurements of plasma parameters in the source and in the extraction regions have been carried out for both cases. Enhancement of H^- and D^- productions is achieved by optimizing plasma parameters for a so-called two-step process of H^- or D^- volume production. It is also confirmed that D^- current is equal to or higher than H^- current under the same discharge conditions, although discharge current is rather low.
