They are the core parts of the injection system and the important guarantee that the Linac beam injecting into the rapid cycling synchrotron (RCS). During the beam commissioning, to check the effect of the residual orbits of the three bumps in the injection region was an important problem. In this paper, the residual orbits of BH and BV painting bumps were studied and estimated in the beam commissioning. The data analysis results showed that the residual orbits of BH and BV painting bumps were very small and they didn’t need to be corrected.
