HIAF project accelerator is composed of intense ion beam sources, injector superconducting LINAC, acceleration and accumulation storage ring, a collection ring and a collider ring. To achieve the ultimate project goal, HIAF accelerator requires the ion source to provide very high intensity of heavy ion beams, such as 1.7 emA 238U³⁴⁺ with a repetition rate of 5 Hz and pulse length of 0.5 ms. No state-of-the-art ion source can meet the needs. As a baseline of the project, a high performance superconducting ECR ion source, which is designed to be operational at the microwave frequency of 40-60 GHz will be adopted to produce the pulsed beam of interest for the HIAF accelerator. To transport and match the beams from ECR to the downstream RFQ, a low energy beam transport (LEBT) is needed. This paper presents a preliminary design of the LEBT and the beam dynamics in the LEBT.
