Abstract：
KONUS beam dynamics design of uranium DTL with LORASR code is presented. The ²³⁸U³⁴⁺ beam, whose current is 5.0 emA, is accelerated from injection energy of 0.35 MeV/u to output energy of 1.30 MeV/u by IH-DTL operated at 81.25 MHz in HIAF project at IMP of CAS. It achieves a transmission efficiency of 94.95% with a cavity length of 267.8 cm. The optimization aims are the reduction of emittance growth, beam loss and project costs. Because of the requirements of CW mode operation, the designed average acceleration gradient is about 2.48 MV/m. The maximum axial field is 10.2 MV/m,meanwhile the Kilpatrick breakdown field is 10.56 MV/m at 81.25 MHz.
