| 内容記述 | An oscillator-type mid-infrared Free Electron Laser (FEL) named as KU-FEL has been developed at the Institute of Advanced Energy, Kyoto University. The extraction efficiency is one of the key parameter of FEL and determines its performance. In this study, the extraction efficiency of KU-FEL was measured by measuring the energy distribution of electron beam with and without FEL lasing at the downstream of the undulator. The measured extraction efficiency was around 5% at the highest power condition of the relative optical cavity length. This value is the highest extraction efficiency observed in an oscillator-type FEL driven by a normal conducting linac. The macro-pulse duration and bunch charge of the linac at KU-FEL are relatively smaller than other facilities. The reason why KU-FEL could achieve such high extraction efficiency was discussed and concluded as the “Dynamic Cavity Desynchronization” in a macro-pulse. |
