	Xi‘an Proton Application Facility (XiPAF) is a new proton project which is being constructed for single-event-effect experiments. It can provide proton beam with the maximum energy of 200 MeV. The accelerator facility of XiPAF mainly contains a 7 MeV H⁻ linac injector and a proton synchrotron accelerator. The 7 MeV H⁻ linac injector is composed of an ECR ion source, a Low Energy Beam Transport line (LEBT), a Radio Frequency Quadrupole accelerator (RFQ) and a Drift Tube Linac (DTL). The 50 keV 10 mA H⁻ beam (pulse width 1ms) extracted from the ion source is expected to be symmetric with the Twiss parameters alpha=0 and β=0.065 mm/mrad. The RMS normalized emittance is required to be less than 0.2 π mm·mrad. With an adjustable collimator and an electric chopper in the 1.7 m-long LEBT, the beam pulse width of 10~40μs and peak current of 6 mA can be obtained. The H⁻ beam is matched into the downstream RFQ accelerator with alpha=1.051 and β=0.0494 mm/mrad. This paper shows the detailed design process of the LEBT and simulation result with the TRACEWIN code.

Xi‘an Proton Application Facility (XiPAF) is a new proton project which is being constructed for single-event-effect experiments. It can provide proton beam with the maximum energy of 200 MeV. The accelerator facility of XiPAF mainly contains a 7 MeV H⁻ linac injector and a proton synchrotron accelerator. The 7 MeV H⁻ linac injector is composed of an ECR ion source, a Low Energy Beam Transport line (LEBT), a Radio Frequency Quadrupole accelerator (RFQ) and a Drift Tube Linac (DTL). The 50 keV 10 mA H⁻ beam (pulse width 1ms) extracted from the ion source is expected to be symmetric with the Twiss parameters alpha=0 and β=0.065 mm/mrad. The RMS normalized emittance is required to be less than 0.2 π mm·mrad. With an adjustable collimator and an electric chopper in the 1.7 m-long LEBT, the beam pulse width of 10~40μs and peak current of 6 mA can be obtained. The H⁻ beam is matched into the downstream RFQ accelerator with alpha=1.051 and β=0.0494 mm/mrad. This paper shows the detailed design process of the LEBT and simulation result with the TRACEWIN code.
