A prototype of a new ion source for neutral beam injection has been developed, which is intended to produce a uniform, high current density ion beam over a large area. Tow channels of discharge electrode rows are used in this source. To drive this source smoothly, two kinds of power supply systems with three-step discharge current controllers are used. Preliminary experiment of ion production were carried out successfully in quasi-steady (2-7s) mode. The ion current density was as high as 0.25 A/cm^2 over such a wide area as 10cm x 15cm with the transverse inhomogeneity less than 10% at a discharge current of 230 A per channel. As compared with the ordinary single-channel ion source, the discharge current per channel required to obtain same ion current density is so small that the life time of the cathode will be much extended.
