For the existing facilities, the status of HIRFL(Heavy Ion accelerator Research Facility of Lanzhou) and Beijing HI-13 tandem accelerator is given. For the proposed next generation high intensity heavy ion facility, the HIAF (High Intensity heavy ion Accelerator Facility) project is introduced. HIAF is a proposed new accelerator facility in China. The facility is being designed to provide intense primary and radioactive beams for a wide range of research fields. The HIAF facility plan was approved by central government of China in December of 2012. The machine studies are now mainly focused on design optimization and key technical R&D. Projected funding for HIAF is estimated to be up to $400 million and the approximately 8-year period is expected to design and construct the facility. The unique features of the first phase of HIAF are high current pulsed beams from iLinac and high intensity heavy ion beams with ultra-short bunch length from CRing. The cooled rare isotope beams also will be prepared through projectile-fragmentation (PF) method and advanced beam cooling technology. To reach the main goals of the HIAF facility, there are still several technical challenges such as operation with high intensity beams, control of the dynamic vacuum pressure, beam compression for very short pulse beam and the design of Nuclotron-type superconducting magnets. For most of those challenges solutions have been found and prototypes are being built through close international collaborations. The general description, accelerator challenges and present status are given in the presentation. PB - JACoW CP - Geneva, Switzerland ER -
