TI - First Simulation Results on Free Electron Laser Radiation in Displaced Phase-combined Undulators J2 - Proc. of FEL2015 AB - This report deals with self amplified spontaneous emission free electron laser (FEL) amplifier where the FEL emission is obtained from displaced phase combined undulators. Magnetic field of this adjustment methods in three dimensions is presented. The electron dynamics is investigated. The simulation method and results are explained. The radiation properties of the fundamental resonance and third harmonic through the phase combined undulators are compared with the normal undulator with the same undulator deflection parameter PB - JACoW CY - Geneva, Switzerland SP - 196 EP - 199 KW - undulator KW - radiation KW - electron KW - resonance KW - FEL DA - 2015/12 PY - 2015 SN - 978-3-95450-134-2 DO - 10.18429/JACoW-FEL2015-MOP068 UR - http://accelconf.web.cern.ch/AccelConf/FEL2015/papers/mop068.pdf ER -
