We present what we believe to be the first automatic alignment of a synchrotron beamline by the Hartmann technique. Experiments were performed, in the soft-x-ray range (E=3 keV, lambda=0.414 nm), by using a four-actuator Kirkpatrick-Baez (KB) active optic. A system imaging the KB focal spot and a soft-x-ray Hartmann wavefront sensor were used alternatively to control the KB optic. The beam corrected with the help of the imaging system was used to calibrate the wavefront sensor. With both closed loops, we focused the beam into a 6.8 microm x 9 microm FWHM focal spot.
我们展示了我们认为是首次通过哈特曼技术对同步加速器光束线进行的自动对准。实验在软X射线范围内（E = 3 keV，λ = 0.414 nm）进行，使用了一个四驱动器柯克帕特里克-贝兹（KB）有源光学元件。交替使用一个对KB焦斑成像的系统和一个软X射线哈特曼波前传感器来控制KB光学元件。借助成像系统校正后的光束用于校准波前传感器。通过两个闭环，我们将光束聚焦成一个半高宽为6.8微米×9微米的焦斑。
