Abstract：
Experimental studies on simultaneous acceleration of O⁺ and O^－ beams have been carried out in a 26MHz integrated SPlit Ring (ISR) RFQ at Peking University. Both O⁺ and O^－ beams can be accelerated to more than 300keV. Output macro-pulse of O⁺ and O^－ was gotten simultaneously at the exit of RFQ when O⁺ and O^－ beams were inputted into the RFQ cavity at the same time. The output micro-pulse beams Of O⁺ and O^－ were measured with a fast target after O⁺ and O^－ beams were accelerated simultaneously in the RFQ. The frequency of micro-pulse is as same as the RF frequency applied to RFQ. The phase difference of O⁺ and O^－ micro-pulse is n that coincides with the anticipated results. The beam current gotten from simultaneous acceleration of O⁺ and O^－ beams are much stronger than that gotten from acceleration of O⁺ or O^－ only.
