The SSC-Linac mainly consists of a 4-rod RFQ and three IH-DTL cavities which can accelerate ion of A⁄q≤7from 3.73 keV/u to 1.025 MeV/u. Both of themoperating at 53.667MHz had been developed. In the commissioning, ions weresuccessfully accelerated to 0.295MeV/u by IH-DTL1. The beam commissioningof the IH-DTL2 which can accelerate the ion to 0.586MeV/u will come soon. In this paper, the recent R&D progress of the SSC-Linac including the development of key components and the beam commissioning results arepresented.
