High-Power Polarization-Controlled Attosecond-Scale Soft X-ray Pulses
Zhaoheng Guo, Carlo Vicario, Andre Al Haddad +18
We demonstrate a versatile platform for high-power attosecond soft X-ray pulse generation with polarization and photon energy control at the SwissFEL free-electron laser. An isolat…

Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern
Linos Hecht, Andre Al Haddad, Björn Bastian +47
We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…

Shapes of rotating normal fluid 3He versus superfluid 4He droplets in molecular beams
Deepak Verma, Sean M. O. O Connell, Alexandra J. Feinberg +15
Previous single-pulse extreme ultraviolet and X-ray coherent diffraction studies revealed that superfluid 4He droplets obtained in free jet expansion acquire sizable angular moment…
