Abstract: Long time KEK superconducting cavities were treated by electro polish at Nomura plating Co.. For developing more reliable EP for ILC SC cavity,KEK decided to construct in-house new EP system. One L-band system and one universal system for 500 MHz and L-band system are gathered in one place.
L-band system have been used routinely ILC cavities EP successfully.
Anther new EP system for 500 MHz KEKB SC cavity have been constructed. KEKB test cavity was successfully processed.
