AB - The ions in a linac, such as ERL, draw more attention recently. LCLSII has a long linac with 1MHz repetition rate. The ions, in general, are not deeply trapped due to the long bunch spacing. The effect of ion thermal energy becomes important in this regime. The beam dynamics with ions are studied numerically. There is a linear growth in amplitude, but not exponential growth as traditional fast ion instability. This instability set a maximum bunch-train length to limit the beam amplitude to fractional beam σ. Theoretical works are also done to compare the simulations. We also extend our works to different regimes where the motions of ions from stable to unstable.
