内容記述(抄録等)Pure volume production of D^- negative ions is studied in rectangular negative ion source equipped with an external magnetic filter (MF). Plasma parameters (n_e and T_e) in D_2 plasmas are varied mainly in the downstream region by changing the magnetic field intensity of the MF (i.e., B_<MF>). Production and control of D_2 plasma is nearly the same as that of H_2 plasmas, although the values of n_e and T_e in D_2 plasma are slightly higher than that of H_2 plasmas in both the source and the extraction regions. On D^-/H^- production, however, it appears some different points. By varying the B_<MF>, H^- production in the extraction region is remarkably changed corresponding to the variation of n_e and T_e in the extraction region. On the other hand, D^- production is not so varied under the same discharge conditions in H_2 plasmas. This difference in D^- production is not well explained only variation of n_e and T_e in D_2 plasmas. Optimum B_<MF> and gas pressure for D^? production is slightly higher than that for H^? production.
