Description
To address the beam quality deterioration of high-energy, high-intensity ion beams in HIAF-BRing caused by heating effects such as intra-beam scattering (IBS), a high-energy electron cooling scheme based on an energy recovery linac (ERL) is proposed. In this scheme, the ERL is used to generate high-quality electron beams, which are then injected into an electron storage ring for multi-turn circulation, allowing repeated interactions with the ion beam to accumulate the cooling effect. The overall layout of the ERL-based cooling system in BRing, the matching of key beam parameters, and the cooling performance are systematically analyzed. Beam dynamics simulations indicate that the proposed scheme can effectively suppress IBS-induced beam heating in the relativistic energy regime and significantly shorten the cooling time, enabling the ion beam quality to meet the design requirements.
