The enhancement of negative ion sources for production of large ion beams is a very active research field nowadays, driven from the demand of plasma heating in nuclear fusion devices and beam compression applications. As a versatile test bench, the ion source NIO1 (Negative Ion Optimization 1) is being commissioned by Consorzio RFX and INFN. The nominal beam current of 130 mA at -60 kV is divided into 9 beamlets, with multiaperture extraction electrodes. Plasma is sustained by 2 MHz radiofrequency. Tests of several magnetic configurations are being prepared. The status of the experiment and related theoretical issues will be described.
