Description

We present, in this paper, the design result of the beam dynamics for a heavy-ion injection line of the Xi’an 200 MeV Proton Application Facility (XiPAF) upgrading project. The heavy-ion injection line consists of an electron cyclotron resonance (ECR) ion source (IS) system, a low energy beam transport line (LEBT), a four-vane radio frequency quadrupole (RFQ) accelerator, an interdigital H-mode drift tube linac (IH-DTL) with an electromagnetic quadrupole (EMQ) structure, and a linac-to-ring beam transport line (LRBT). The injection line can provide 2 MeV/u heavy-ion beams which will be injected into the synchrotron via multi-turn injection through an electrostatic septum. The characteristics of the injected beam are validated using the TraceWin code to ensure they meet the specifications for transverse emittance, momentum spread, mismatch factor of Twiss parameters, and beam dispersion.
