	Beam profile is a key parameter for high current proton linac. Compact Pulsed Hadron Source(CPHS) has two type of detectors to monitor beam 2D beam profile: scintillator screen and rotatable multi-wire scanner. A retractable chromium-doped alumina (Chromox) screen is used as scintillator, emitted lights when impacted by proton are captured by a 12 bit CCD camera. Nineteen carbon fibre wires with a diameter of 30 'm, 3 mm separated from each other, are used to measure beam 1D distribution. Projection can be measured at different direction by rotating the multi-wire scanner about beam direction. 2D beam distribution is reconstructed from multiple projections with the help of CT. Different CT algorithms, Algebra Reconstruct Technique (ART) and Maximum Entropy algorithm (MENT), are applied to achieve accurate or quick reconstruction. The preliminary experimental results show the two profile monitors working consistently with each other.

	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.
