Abstract

We report on our high speed camera designed for temporal characterization of attosecond pulses (1as =10^-18s) generated with the polarization gating technique. The uniform external magnetic field applied on the time-of-flight spectrometer enlarges the acceptance angle (up to 65° for ~20-eV photoelectrons). By collecting two-dimensional momentum images of the photoelectrons, which are ejected by the XUV pulses and streaked directly by the co-propagating polarization gating electric field, we expect to derive the information about the XUV pulses. After the characterization of XUV pulses, the same setup can be used to study complex dynamics of electrons in atoms and molecules with time-resolved spectroscopy.
