  2. radiation properties from planned PWFA and plasma in-jector experiments at FACET-II. Spatial and temporal pro les of radiation are also important to study orbital angular momentum of light, microscopy of lights [23]. In Sec.II, we lay out a limited analytical description of the betatron radiation generated by a Gaussian beam in an ion channel.

    The helical motion driven by the laser rotation is found to dominate the radiation emission, rather than the betatron oscillations. Moreover, the radius of this helical motion can be controlled through the laser spot size and orbital angular momentum indexes, meaning that the radiation can be tuned fully independently of the plasma parameters.

    We present the first measurements of the angular dependence of the betatron x-ray spectrum produced by electrons inside the cavity of a laser-wakefield accelerator. Electrons accelerated up to 300 MeV energies produce a beam of broadband, forward-directed betatron x-ray radiation extending up to 80 keV. The angular resolved spectrum from an image plate-based spectrometer with differential ...

On-axis betatron radiation passes through a hole in the pro ler and is detected by the x-ray camera, which is separated from the interaction chamber by a beryllium window. An aluminum lter foil attenuates the betatron ux.
