Laser wakefield accelerators have great potential as the basis for next generation compact radiation sources because of their extremely high accelerating gradients. However, X-ray radiation from such devices still lacks tunability, especially of the intensity and polarization distributions. Here we propose a tunable polarized radiation source based on a helical plasma undulator in a plasma channel guided wakefield accelerator. When a laser pulse is initially incident with a skew angle relative…

Optical control of hard X-ray polarization by electron injection in a laser wakefield accelerator

This work shows that it can measure and control the polarization of ultra-short, broad-band keV photon pulses emitted from a laser-plasma-based betatron source, and expects that this method for an all-optical steering is not only useful for plasma-based X-ray sources but also has significance for future laser-based particle accelerators.
