• A field-emission liquid Alion source with a sintered boride emitter, such as TiB_2, BN-TiB_2 composite, has been built to prolong the utilization term of an aluminum ion beam emission. In this approach, a stable Al ion beam emission was successfully obtained for more than 100 hours without any recognizable degradation. Emission current fluctuation was less than ±1% over 1 hour for 10 μA source ion current without any feedback stabilization. Moreover, 20-30 μA/sr angular intensity at 5-10 μA source ion current, 17° emission half-angle at 10 μA source current, and a large source ion current of more than 1.5 mA were also observed.
