  A superconducting proton linear accelerator for Chinese ADS have been proposed by IMP CAS. The preliminary beam dynamics design is finished. The RFQ is designed to be operated at CW mode will accelerate 10 mA proton from 35 keV to 2.1 MeV. The acceleration rate of RFQ is 95.2% with the length of 4.5 meters. The 99.9 % longitudinal emittance at the RFQ exit is optimized to 4.98 pi.mm.mrad and 0.18 times of the longitudinal acceptance of downstream superconducting accelerator. These goals of RFQ beam dynamic studies usually are minimize the vane length, beam loss and emittance growth. But the 99.9 % longitudinal emittance of RFQ is proposed as the new and key optimization goal to reduce the possibility of downstream beam loss for the RFQ which is in the front of superconducting linear accelerator. The 99.9 % longitudinal emittance is optimised at the cost of RFQ transmission rate though three steps. First, the optimised longitudinal phase space is got by the long and stable shaper section. Second, Smaller longitudinal acceptance is adopted to make particle loss in low energy section. third, the shrink of longitudinal acceptance is optimised to get lower 99.9% longitudinal emittance.

  A new heavy ion superconducting linac, named Super-Conducting Ion Linac(iLinac) has been proposed and designed in the Institute of Modern physics of China. As the injector of High intensity heavy Ion accelerator facility (HIAF), iLinac will accelerate the 1 mA 238U45+ beam to 17 MeV/u. In this paper, we will focus on the physics design study together with the design principles and the simulation results with machine errors.
