Air attenuation of high power XFEL beams

Journal of Synchrotron Radiation, EarlyView.
The transmission of air, which is used to contain X‐ray beams for radiation safety, is observed to significantly increase with X‐ray power.The Linac Coherent Light Source II, a high‐repetition‐rate X‐ray free‐electron laser (FEL), produces high average power as well as high peak power.
