In a volume negative ion source, H/sup -/ ions are formed in hydrogen plasmas by dissociative attachment of slow plasma electrons to highly vibrationally excited hydrogen molecules, and these vibrational molecules are produced by energetic electron impact. Production of D/sup -/ ions is believed to be the same as that of H/sup -/ ions. To develop efficient D/sup -/ ion sources, it is important to study production and control of D/sub 2/ plasmas, and to understand difference in the negative ion volume production between H/sub 2/ plasmas and D/sub 2/ plasmas. For this purpose, we discuss isotope effect of H/sup -//D/sup -/ production and to clarify the dependence of negative ion production on plasma parameters by measuring negative ion densities in the source.
