在激光驱动的等离子体加速器的电子感应加速器振荡产生的X射线的特点和应用于成像工业样品。在125 TW激光器下,产生了一束每脉冲5.2±1.7× 107光子mrad− 2的低发散光束,其同步辐射谱的临界能量为14.6±1.3 keV。获得计量测试样品、电池电极和复合材料中的损伤部位的射线照片。这些结果证明了非破坏性评估应用的源的适用性。等离子体加速器的工业实施的潜力进行了讨论。
X-rays generated by betatron oscillations of electrons in a laser-driven plasma accelerator were characterised and applied to imaging industrial samples. With a 125 TW laser, a low divergence beam with 5.2±1.7× 10 7 photons mrad− 2 per pulse was produced with a synchrotron spectrum with a critical energy of 14.6±1.3 keV. Radiographs were obtained of a metrology test sample, battery electrodes, and a damage site in a composite material. These results demonstrate the suitability of the source for non-destructive evaluation applications. The potential for industrial implementation of plasma accelerators is discussed.
