KEK has been designing the 10 mA class ERL-EUV light source accelerator. The main linac uses 9-cell superconducting cavities with beamline HOM damper. The target accelerating gradient is 12.5 MV/m. The 9-cell cavity is designed from experience of the KEK compact ERL (cERL) main linac. The cERL main linac was designed to suppress the HOM-BBU with beam current of 100mA by enlarging the iris...

Suppression of the higher order modes (HOMs) is one of the most critical issues in an accelerator dealing with the intense bunches and the high beam repletion rate. In a superconducting (SC) machine like the LCLS-II, intense short bunches passing through SC cavities (1.3 GHz and 3.9 GHz 9-cell ), interconnecting cavity bellows and beam pipe transition at intermediate warm sections excites the...
