The design and construction with several tens of megawatts superconducting accelerator is the developing direction in the further. The superconducting section follows the RFQ and MEBT, which needs good enough beam quality. The normal temperature front ends are redesigned for China Initiative ADS. The LEBT transports a 35KeV, 10mA DC proton beam to the RFQ, after the RFQ acceleration the MEBT transports a 2.1MeV 10mA CW proton beam to the superconducting DTL. The "Point Source" is proposed in

To get the ideal longitudinal beam parameters, the new RFQ is designed with little emittance. Collimators are installed in the new MEBT to scrape the outer sphere beams which may turn to halo. Details of the beam dynamics simulations will be given.
