Abstract：
The measurement method and principle of dipole magnet reproducibility for Cooling-storage-ring are introduced. How the position and number of steel sheet affect the reproducibility of magnet is investigated. In the end, the reproducibility of CSRm dipoles reaches to less than ±2×10-4, which can meet the acquirements of CSR. In addition, the measurement repeatability and the sources causing errors are also analyzed.
