abstract = {Refractive X-ray lenses are frequently used components at
modern X-ray free-electron laser facilities. This work
investigates the temporal effects of refractiveoptics on
ultra-short X-ray pulses, particularly focusing on pulse
elongation. Wepresent a model using full Fresnel theory to
study the beam profile at the focusin space and time.
Refractive X-ray lenses not only change the
temporalstructure of the pulse, the focus size is also
dependent on the incoming pulseduration. Further, we present
a simplified ray-tracing model to estimate thepulse
stretching effect of compound refractive lenses (CRLs),
which we find tobe dependent only on the dispersion and the
absorption of the CRL materia},
