  We present, in this paper, the design result of the 7 MeV linac which will inject the negative hydrogen ion beam to the downsteam synchrotron of the Xi‘an Proton Application Facility (XiPAF). This newly designed facility will be located in Xi'an city and provide the proton beam with the maximum energy of 230 MeV for the research of the single event effect. The 7 MeV linac injector is composed of the 50 keV negative hydrogen ion source, Low Energy Beam Transport line (LEBT), 3 MeV four-vane-type Radio Frequency Quadrupole (RFQ) accelerator, 7 MeV Alvarez-type Drift Tube Linac (DTL), and the corresponding RF power source system. The output beam of the linac injector is designed with the peak current of 5 mA, maximum repetition frequency of 0.5 Hz, beam pulse width of 10~40 μs and RMS normalized emittance of 0.24 π mm·mard.

  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.
