摘要
H-/D- production in a pure-volume source has been studied. In our double plasma device, both energy and density of fast electrons are well controlled. With the use of this source, the enhancement of H-/D- production has been observed. Namely, under the same discharge condition, the extracted H-/D- current in the double plasma operation is higher than that in the single plasma operation. Besides these, for the same discharge conditions, negative ion current is found to be higher in D2(-) discharge than in H2(-) discharge.
