	Energy recovery linac(ERL)-based free electron lasers(FELs) are promising candidates for high-power EUV sources. They can recover most acceleration energy from the electron beams and greatly reduce the dumped beam power and activation compared with those based on ordinary linear accelerators. We have investigated a feasible design of a 10-kW class ERL-FEL operated at 13.5 nm for EUV lithography applications. In this talk, we will present the design work of the ERL-FEL as the high-power EUV source.

	We developed ERL injector cryomodule and main linac for Compact ERL (cERL) project. 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.
