在100-TW激光等离子体相互作用中观察到长尺度射流x射线发射。射流准直良好，发散度为30-40 mrad，在激光的镜面方向上从目标表面持续到低密度区域，距离超过4 mm。二维粒子胞内模拟表明，激光镜面反射使电子加速，电子流被自生磁场准直，导致电子向镜面反射光方向喷射。
Long-scale jetlike x-ray emission was observed in a 100-TW laser-plasma interaction. The jet was well collimated with a divergence of 30-40 mrad and continued from the target surface into underdense regions for a distance over 4 mm in the specular direction of the laser light. A two-dimensional particle-in-cell simulation shows an electron acceleration with the specularly reflected laser light and collimation of the electron stream by a self-generated magnetic field, resulting in the electron jet to the direction of the specularly reflected light.
