The LCLS is capable of the shortest x-ray pulses in the world. In this talk, Ryan Coffee will discuss how these short pulses can be used to move x-ray spectroscopy into the time domain. Specifically, he will discuss Auger electron spectroscopy in the reference frame of a molecule and then present a time-domain measurement of resonant "bleaching" of an x-ray transition. The latter constitutes the LCLS team’s first attempt at x-ray transient absorption spectroscopy in the few femtosecond regime.

Speaker:
Ryan Coffee, LCLS
Ryan Coffee works with the interactions of small molecules with strong laser fields. His background lies in Ti:Sapphire laser driven multiple ionization of nitrogen. Ryan studied the Coulomb fragmentation with ion time-of-flight spectroscopy as well as vacuum ultraviolet fluorescence spectroscopy. Since coming to PULSE, Ryan has added cell based experience with the strong field impulsive alignment of iodine.
