STATUS OF DEVELOPMENT OF THE CERL SUPERCONDUCTING

Development of the superconducting injector linac for the compact ERL has been continuing at KEK. The cryomodule including three two-cell SC cavities was designed. Two prototype two-cell cavities were fabricated, and the vertical tests within without HOM pick-up probe were carried out after the standard surface preparation at KEK-STF. The status of the component for the cERL injector linac will be reported.
