The duoplasmatron ion source of the Livermore 400 kV ICT accelerator was modified to increase the target current from the accelerator. In routine operation, D$sup +$ currents on target of 18 to 22 mA are now produced rather than the 5 to 8 mA originally available. The major modification to the source was the installation of a focus electrode between the plasma expansion cup and the accel-decel extraction electrode system. With this arrangement, the source output may be varied from maximum down to zero beam level without excessive extractor loading. Beam divergence varies from 6 mrad to 30 mrad. The focusing and extraction electrodes are simple to fabricate and are radiation cooled. Beam transport efficiency of 75 percent was obtained through the 15 m long x 10 cm diameter transport system. The increase in target current was obtained without decreasing the reliability of the accelerator. (auth)
