Self-seeding scheme for the soft X-ray line at the European XFEL
Self-seeding scheme soft X-ray line the European XFEL
2012/2/28
This paper discusses the potential for enhancing the capabilities of the European FEL in the soft X-ray regime. A high longitudinal coherence will be the key to such performance upgrade. In order to r...
Circular polarization control for the European XFEL in the soft X-ray regime
XFEL Circular polarization European
2011/8/31
The possibility of producing X-ray radiation with high degree of circular polarization is an important asset at XFEL facilities. Polarization control is most important in the soft X-ray region.However...

Local electronic structure of Fe$^{2+}$ impurities in MgO thin films: Temperature-dependent soft x-ray absorption spectroscopy study
Local electronic structure of Fe$^{2+}$ impurities Temperature-dependent soft x-ray absorption spectroscopy study
2010/11/18
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state.The fi...
Rare-gas clusters in intense VUV, XUV and soft x-ray pulses: Signatures of the transition from nanoplasma-driven cluster expansion to Coulomb explosion in ion and electron spectra
VUV XUV soft x-ray pulses
2010/11/16
We investigate the wavelength dependent ionization, heating, and expansion dynamics of medium-sized rare-gas clusters (Ar$_{923}$) under intense femtosecond short-wavelength free electron laser pulse...
Transmission measurement of photo-absorption cross section of aluminum in soft X-ray region of 50 to 250eV
synchrotron radiation soft-X-ray aluminum thin-film photo-absorption cross section
2009/8/13
The photo-absorption cross section of aluminum was obtained from the ratio of transmission of aluminum thin-films with different area densities from 50 to 250eV with synchrotron radiation monochromati...
