摘要：
Betatron radiation based on laser-plasma accelerator has properties of collimated, ultrafast, small sources size, high brightness, and broad energy spectrum. These features make it suitable for many applications, such as phase-contrast imaging or X-ray absorption spectroscopy. In this paper, we present two methods to improve the photon energy and photon number of betatron radiation. As a result, high-brightness photon sources with high yield, adjustable photon energy range from hard X-ray to gamma ray and polarization were generated. The main reason for the enhancement is due to the accelerated electrons efficiently wiggling in a laser field.
