In 2005, the commissioning totally 60 days for the CSR main ring was performed, the first-turn and stored C^6＋ beam （with lifetime more than 10 s） in the CSRm were achieved with ≈ MeV/u ^12C^4＋ as the injection beam. Many technical progresses have been made before realizing the storage of ion beam, such as the control of magnet power supplies,
