Measuring cluster ion beam transmission as a function of the target gas density at a charge exchange section in a tandem accelerator allows us to determine cross sections for collision-induced destruction and a charge exchange from a negative ion (q = -1) to a positive ion (q = +1). Using the TIARA 3MV tandem accelerator, we evaluated the cross sections for carbon cluster ions C(n=4, 8) in MeV energy regions on several gas targets (He, N, CO, SF). As a result, it was revealed that the destruction cross sections and the charge exchange cross sections for C and C were on the order of 10 $^{-15}$ cm and 10 $^{-16}$ cm, and on the order of 10 $^{-14}$ cm and 10 $^{-16}$ cm, respectively.
