The extraction efficiency is one of the key parameter of FEL and determines its\nperformance. In this study, the extraction efficiency of KU-FEL was measured by measuring the energy distribution of\nelectron beam with and without FEL lasing at the downstream of the undulator. The measured extraction efficiency was\naround 5% at the highest power condition of the relative optical cavity length. This value is the highest extraction\nefficiency observed in an oscillator-type FEL driven by a normal conducting linac. The macro-pulse duration and bunch\ncharge of the linac at KU-FEL are relatively smaller than other facilities. The reason why KU-FEL could achieve such\nhigh extraction efficiency was discussed and concluded as the “Dynamic Cavity Desynchronization” in a macro-pulse.
