Its accelerator consists of an H⁻ injector and a proton Rapid Cycling Synchrotron. The injector includes the front end and linac. The RFQ accelerates the beam to 3MeV, and then the Drift Tube Linac (DTL) accelerates it to 80MeV[1]. An Medium Energy Beam Transport (MEBT) matches RFQ and DTL, and the DTL consists of four tanks. Commissioning of the MEBT and the first DTL tank (DTL1) have been accomplished in the last run. Due to the difference of actual effective length and theoretical effective length of magnets in MEBT and DTL1, in order to compare its impact of beam transport, this paper takes a beam dynamics simulation on beam transport in MEBT and DTL1 with IMPACT-Z code[2]. Meanwhile, the transport of beam with different emittance in MEBT and DTL1 is studied because of the large emittance at RFQ exit. All the simulation includes magnet error and RF error.
