Although optimizing the magnetic filter position and the plasma grid potential is one of the most effective factors to enhance H- yield, details concerning their roles are not now clarified well. In this article, spatially resolved measurements of the electron energy distribution function, plasma fluctuations, and plasma parameters are presented. On the basis of these experimental results, we will discuss the roles of both the magnetic filter and the plasma grid biasing voltage Vb on enhancement of H- production and extraction of H- ions.
