چکیده انگلیسی
The Pohang Accelerator Laboratory X-ray free electron laser (PAL-XFEL) will operate a soft X-ray undulator line and a hard X-ray one during the initial operation period. For the hard X-ray line, self-seeding using a diamond crystal is the most promising approach to supply narrow bandwidth radiation to users. This paper presents simulation results for the optimization of the self-seeding layout in the hard X-ray undulator line for PAL-XFEL. The electron energy used in this study for the hard X-ray self-seeding scheme is 8.126Â GeV and the central wavelength is 0.15Â nm. The photon beam spectral bandwidth will be 0.78Â eV by using the self-seeding option.
