	We report a design of the 230 MeV proton accelera-tor, the Xi’an Proton Application Facility (XiPAF), which will be located in Xi’an city, China. The facility will provide proton beam with the maximum energy of 230 MeV for the research of the single event effect. The facility, composed of a 230 MeV synchrotron, a 7 MeV H⁻ linac injector and two experimental stations, will provide a flux of 10⁵~10⁸ p/cm²/s with the uni-formity of better than 90% on the 10 cm×10 cm sample.

	The CPHS (Compact Pulsed Hadron Source) linac at Tsinghua University, is now in operation as an achievement of its mid-term objective. Presently the RFQ accelerator is operated stably with the beam energy of 3 MeV, peak current of 26 mA, pulse length of 100 μs and repetition rate of 20 Hz. After the maintenance period the transmission rate of the RFQ accelerator has been recovered from 65% to 91%. The application of the proton and neutron beam is introduced in this paper.

	The 7 MeV H⁻ linac injector of Xi‘an Proton Application Facility (XiPAF) 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 1.7 m-long LEBT is used for matching a 40 μs pulse width 6 mA peak current beam to the entrance of the RFQ accelerator. The peak current and pulse-width of the 50 keV H⁻ beam extracted from the ion source is 10 mA and 1 ms respectively. In the LEBT, an adjustable aperture is used for scraping the peak current of the beam to 6 mA, and an electric chopper is used for chopping the beam pulse width to 40 μs. These elements make the space charge compensation problem more complicated. A careful simulation of the space charge compensation problem of the H⁻ beam has been done by considering the beam particles interacting with the residual gas with the help of WARP PIC code. To achieve the requirements of the LEBT in XiPAF, the type and pressure of the residual gas is given according to the simulation results.
