A high current O+ ion source is desirable for applications to SIMOX and materials modification. To meet the requirements of this field, a new type of nonfilament high current O+ ion source has been developed successfully in our institute. Using O2 as discharge material, the typical extraction characteristics are as follows: The total oxygen ions current is 100 mA, of which the content of O+ is 80%, beam current density is larger than 200 mA/cm2 when the power consumption is 100 W; therefore the economic property is 1 mA/W. Feeding N2, the total extraction beam current is 100 mA of which 70% is N+ while the power consumption is 135 W.
