Scientific Reports

Using electron spectroscopy, we have investigated nanoplasma formation from noble gas clusters exposed to high-intensity hard-x-ray pulses at ~5 keV. Our experiment was carried out at the SPring-8 Angstrom Compact free electron LAser (SACLA) facility

Photoelectron angular distributions (PADs) dependence on the time-delay between EUV-FEL and IR laser pulses is observed for ionization of Ne. PADs for Rydberg excited oneand two-IR photon above-threshold ionization of He are measured. Ultrafast Pheno

Via extreme ultraviolet free electron laser pump and near infrared laser probe experiments for rare-gas clusters, we found clear enhancement of highly charged ions when EUVFEL and NIR pulses overlap, indicating efficient heating of nano-plasma.

We have measured electron energy spectra and asymmetry parameters of Ar clusters and Xe clusters illuminated by intense x-rays at 5 and 5.5 keV. A velocity map imaging spectrometer was developed for this purpose and employed at an x-ray free-electron
