The radio-frequency (RF) phase effect has been studied on the current profile after the chicane and on the x-ray radiation power at 50 m along the undulator. This study leads to the tolerance in the RF phase. The results show that a single isolated attosecond radiation pulse could be produced inside the undulator; however, the RF phase should be controlled down to 0.05° in the linac section of the PAL-XFEL in order to satisfy the requirement for RF jitters suitable for pump–probe experiments.</p> 2013-08-13 00:00:00 ESASE scheme attosecond radiation pulse nm fwhm RF phase chicane laser undulator Atomic Physics Molecular Physics
