本文报道了一种采用电荷耦合器件（CCD）的高速直接X射线探测系统。它可以以每秒一百万像素的速度从CCD获得数字输出。通过适当的图像大小，我们可以以电影的速度获得图像。我们所采用的CCD具有比光学用CCD更厚的耗尽区。我们的系统可以获得能量分辨的X射线图像。我们使用针孔摄像系统证明了它的有效性，并获得了用Fe-K和Ti-K X射线分辨的图像。图像质量不是由CCD的像素大小（12×12 µm2）决定的，而是由我们使用的针孔大小（直径200 µm）决定的。我们的系统是一个很有前途的焦平面探测器的X射线光学，如X射线显微镜。
We report here a high-speed direct X-ray detection system using the charge-coupled device (CCD). It can obtain digital output from the CCD at a speed of one million pixels per second. With an appropriate image size, we can obtain images at the speed of a movie. The CCD we employed has a thicker depletion region than that of the optical-use CCD. Our system can obtain energy-resolved X-ray images. We demonstrated its validity using the pinhole camera system and obtained images resolved with Fe-K and Ti-K X-rays. The image quality was determined not by the pixel size of the CCD (12×12 µm2) but by the pinhole size (200 µm in diameter) that we used. Our system is a promising focal plane detector for X-ray optics such as an X-ray microscope.
