The injector cryomodule includes three 2-cell L-band superconducting cavities. The main linac cryomodule includes two 9-cell L-band superconducting cavities. After construction of cERL injector and recirculaton loop, beam operation was started with 20 MeV beam and after precise beam tuning, energy recovery operation was achieved with more than 80uA. Injector and main linac cavity were stable for ERL beam operation with Digital LLRF system. Field emission is the severe problem for main linac and heating of HOM coupler is the problem for injector. We mainly describe the cavity performances of two cERL cryomodules during long-term beam operation.
