The HIAF front end will provide beams of ions with a mass up to uranium at a beam energy of 0.5 MeV/u. The required intensity of uranium beam is of 30 pμA and the charge state is 35+. This paper presents a design of HIAF front end, which includes three ECR ion sources, LEBT, RFQ and MEBT. Beam transmission and dynamics studies have been performed and will be described. These studies include beam extraction simulation from ECR ion source, space charge compensation in LEBT, LEBT beam dynamics with a achromatic system, beam collimation in LEBT, RFQ beam dynamics with pre-bencher. In addition, end-to-end beam simulations have also been carried out to evaluate the front end performance. PB - JACoW Publishing CP - Geneva, Switzerland ER -
