Abstract：
Due to the errors in all kinds of components of a storage ring, the real optics of the ring is different from the design one. A method that fit the measured response matrix to the model response matrix is developed to calibrate the linear optics. This paper introduces some applications at the BEPC. By analyzing the measured response matrix, we have corrected the local closed orbit successfully. On the other hand, simulation study shows that it is feasible for BEPC to determine the real quadrupole gradients, orbit corrector strengths, and BPM gains using response matrix.
