Abstract：
Experimental studies were conducted to characterize and improve the performance of the flat-B ECR ion source. The emittance of the source was investigated for the first time. The output beam currents of high-charge-states of Ar (q>8) were nearly doubled by increasing the plasma electrode aperture from 4mm to 6mm in diameter. To investigate possible enhancements with broadband microwave radiation, a "white" Gaussian noise generator was employed with a TWT amplifier to generate microwave radiation with a bandwidth of ～200MHz. The performance of the flat-B ECR ion source was found to be much better with narrow bandwidth radiation when the source was operated in the flat-B region. However, the ion beam intensities and charge state distributions were improved with the broadband radiation when the source was tuned {off} the flat-B region.
