abstract = {{A Low Energy heavy ion Accelerator Facility LEAF has been built at IMP. Aiming to prototype the room temperature front end of High Intensity Heavy Ion Accelerator Facility (HIAF)* and also serve as a stand-along operation facility for multi-discipline physics researches using high intensity low energy heavy ion beams, LEAF can accelerate high intensity ion beams of M/q=2~7 up to 0.7 MeV/u, typically >1 emA U³⁴⁺. The LEAF 81.25 MHz 4-vane RFQ** has been fully commissioned to its design power. Machine study with the ion beams of M/Q=2~7 has been completed, and the typical transmission efficiency of the RFQ can reach 97%. An acceleration efficiency of 85% for heavy ion beams can be made with a multi-harmonic buncher (MHB). With a superconducting ECR ion source, highly charged uranium ion beams are available that enables the successful acceleration of high intensity uranium ion beams with LEAF. This paper will present the design and preliminary commissioning results of the facility, and future plan of an IH type DTL to tune the output energy will also be discussed.}},
