The production of negative hydrogen ions, H^-, has been experimentally studied using a multipole-type hydrogen-plasma device. The dependence of the density of H^- on the heater current, the discharge current and the hydrogen gas pressure was investigated by measuring the energy distribution. The density of H^- was determined from the height of a sharp peak of the second derivative of the langmuir probe characteristic, which corresponded to the H^- current. The optimum value of these parameters could be found for the production of H^-. Primary electrons contributed largely to the production of H^-, whereas thermal electrons had little effect.
