We investigated the design of post linac to driver linac transport beam line(P2DT) in the Rare Iso- tope Accelerator (RAON). P2DT beam line is designed a form of 180-degree bending to send the radioactive ISOL beams accelerated in the Linac-3 to Linac-2. The beam line is designed for the transport of a multi-charge state 132Sn+45,+46,+47 beam. The main characteristics of the P2DT line is to minimize beam loss and the growth of emittance, and charge stripping. We used the TRACE 3-D, TRACK, and ORBIT codes to design the optics system. This beam line includes two bunch- ers and ten sextupole magnets for chromaticity compensation. The transverse emittance growth is minimized by adopting mirror symmetric optics, and by correcting second-order aberrations using sextupoles. We report on the multi-charge state beam transport performance of the designed beam line. Beam optics for P2DT is optimized for reduce beam loss and charge stripping. State of the beam are examined when the errors occur in the magnets for the real case. The condition of beam is optimized by orbit correction using correctors and monitors. In this paper we focus on the beam dy- namics and error studies dedicated to the P2DT beam line and show the optimized beam parameters in P2DT.
