Abstract

An electron outcoupling scheme was proposed for the high power FELs with optical cavities to avoid the power limitation because of overheating of the reflecting mirrors. This can be realized if the major part of radiation power is emitted at an angle to the optical axis. For this, the electron beam should be bunched and then slightly rotated in an undulator of the FEL. At the NovoFEL facility, the electron outcoupling system is installed on the third FEL, based on the multi-turn energy recovery linac. It consists of three undulators, dipole correctors, and two quadrupole lenses assembled between them. There are two different configurations of the system, with electrons deflected in either the second or the third undulator. The electron beam dynamics calculations, current experimental results, and planned experiments are discussed.
