Abstract：
An ECR O⁺ ion source and LEBT system have been developed for the upgrade of 1MeV Integral Split Ring RFQ at Peking University. To satisfy the requirement of RFQ, a more than 10mA oxygen beam has been extracted at 22kV through a 5mm diameter aperture. Its normalized root-mean-square emmitance is less than 0.1π.mm.mrad, which is required by RFQ accelerator. The LEBT matching section is redesigned upon the bench test results. The preliminary results will be presented in this paper.
