Frequency Chirped SASE FEL
We present a statistical analysis of the temporal and spectral properties of SASE radiation from an energy-chirped electron beam passing through a long undulator. It is found that the coherence time is independent of the chirp, while the range of spectral coherence is linearly proportional to it. We consider the use of a monochromator to pick out a small temporal slice of the radiation output. ...
متن کاملStorage Ring Design Optimization for Fel Operation
An electron beam in a storage ring seems to be a perfect driver for a free electron laser. The understanding of storage rings is very well advanced to.project designs with high peak current, small beam sizesand short damping times. Since the beam is recycled after passage through the optical cavity we can expect a relatively high overall efficiency. On the other hand, however the fact that we d...
متن کاملRadiation Pulse Compression for a SASE-FEL
The total radiation pulse consists of NS spikes, and the total pulse length is LP=NSLc. In a normal configuration all the spikes have the same line-width and the same central frequency. Chirping the pulse, i.e. changing the frequency of each spike by a quantity proportional to the spike longitudinal position inside the pulse, allow us to compress the pulse using a pair of diffraction gratings. ...
متن کاملOptimization of an X-ray SASE-FEL
The most important characteristics of an X-ray SASE-FEL are determined by the electron beam energy, transverse and longitudinal emittance, and by choice of the undulator period, field, and gap. Among them are the gain and saturation length, the amount and spectral characteristics of the spontaneous radiation, the wake fields due to the vacuum pipe. The spontaneous radiation intensity is very la...
متن کاملSASE FEL Saturation Characterization at the ATF
After successful completion of the High Gain Harmonic Generation (HGHG) free electron laser (FEL) experiment [1,2] at the Accelerator Test Facility (ATF), R&D toward future light sources at the NSLS achieved another milestone on March 17, 2001 when the visible-infrared self-amplified spontaneous emission amplifier (VISA) experiment at the ATF achieved saturation. The VISA Self Amplified Spontan...
