	The post accelerator of RAON can accelerate the unstable and stable ion beams up to 15 MeV/u for 132Sn¹⁶⁺ and 58Ni⁸⁺ for 16.5 MeV/u, which has the ratio of mass to charge, A/q, of 8.3. The unstable ion beam such as 132Sn¹⁶⁺ produced by an ISOL system has the large transverse and longitudinal emittances. The post-accelerator consists of post-LEBT, RFQ, MEBT and superconduction linac(SCL3 and we optimized acceptance and beam envelope based on the beam dynamics in the linac. The accelerated beam by post accelerator was transported by the post-to-driver transport (P2DT) line which consists of a charge stripper, two charge selection sections and a telescope section with the bunching cavities to the high energy linac(SCL2) and accelerated up to 200 MeV/u. In this presentation, we will show the criteria for the design of the post accelerator and result of beam tracking simulation from post-LEBT to end of high energy linac.

The post-accelerator consists of post-LEBT, RFQ, MEBT and superconduction linac(SCL3 and we optimized acceptance and beam envelope based on the beam dynamics in the linac. The accelerated beam by post accelerator was transported by the post-to-driver transport (P2DT) line which consists of a charge stripper, two charge selection sections and a telescope section with the bunching cavities to the high energy linac(SCL2) and accelerated up to 200 MeV/u.
