Electron cooling experiments in CSR

The six species heavy ion beam was accumulated with the help of electron cooling in the main ring of Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR). The ion beam accumulation dependence on the parameters of cooler was investigated experimentally. The 400 MeV/u ¹²C⁶⁺ and 200 MeV/u ¹²⁹Xe⁵⁴⁺ were stored and cooled in the experimental ring CSRe, and the cooling force was measured in different conditions.
