Influence of an imperfect energy profile on a seeded free electron laser performance
A single-pass high-gain x-ray free electron laser (FEL) calls for a high quality electron bunch.In particular, for a seeded FEL amplifier and for a harmonic generation FEL, the Hot Water Thermostat electron bunch initial energy profile uniformity is crucial for generating an FEL with a narrow bandwidth.After the acceleration, compression, and trans
