Charge-state transition of accelerating ions occurs in the beam line due to interaction with the residual gas. Since this exchange changes charge to mass ratio of the ions, the ion orbit is distorted especially in an arc section with the ion potentially hitting the vacuum pipe. This will generate outgassing from the beamline pipe. Moreover, they become a seed of further charge-state exchanges. Therefore, a collimation of charge exchanged ions is necessary to prevent this feedback cycle. In this presentation, the results of a simulation study on charge exchange reaction in the 1st arc section of FRIB and optimization of collimator position are presented.
