Description

We started beam operation with Compact ERL(cERL) main linac cryomodule from 2013.Dec. Until now, we succeeded energy recovery with 80 uA CW beam current of 20 MeV. For stable beam operation with more high current CW beam, it is necessary to know the phenomina inside the superconducting cavity during beam operation, for example, increasing field emission. In order to know these phenomina, several fast monitors were set and monitored when the unexpected trip and/or radiation increase were occurred with beam. In this paper, we describe the details of long-term operation experience of these cavities by using these monitors. (author)
