Abstract
We present, in this paper, the development progress of the 7MeV Linac for the 200MeV synchrotron of the Xi'an Proton Application Facility (XiPAF). 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 2.45 GHz microwave-driven Cesium-free Electron Cyclotron Resonance (ECR) source and LEBT will be commissioned in this year, and the peak current of the extracted H⁻ beam at the exit of the LEBT is expected to be 6 mA, with the output energy of 50 keV, maximum repetition rate of 0.5 Hz, beam pulse width of 10~40 microseconds and normalized RMS emittance of less than 0.2 PI mm mrad. Furthermore, the construction status of the RFQ accelerator and DTL accelerator will be presented in this paper.
