Date & Time: Apr 2 2021 | 11:30am Location: ONLINE ONLY X-ray Free Electron Lasers (XFELs) produce high intensity X-rays with attosecond pulse durations by “undulating” an electron beam at high speeds. The generation of these X-ray pulses allow for Attosecond Pump-Probe Spectroscopy to be used on dilute, gas phase samples. However, XFELs have a problem with shot to shot spectral variation, and due to this, they are not well suited to absorption measurements. To combat this, researchers at the Stanford Linear Accelerator Center (SLAC) have implemented principals used in an imaging technique known as “Ghost Imaging” to simultaneously collect an absorption measurement and the spectra of the pulse in order to correct for the XFEL’s instability.
