摘　　要：采用自编写的图像处理程序把中国地图处理成为边界点阵图,并根据点阵图每点的坐标位置,利用中国第1台单粒子束精确定位照射装置提供的单质子束在CR-39膜上几百μm×几百μm的范围内辐照并刻蚀出中国地图边界.研究表明,该单粒子束精确定位照射装置计数准确(98%),定位精确(平均误差小于3μm),辐照路径算法选择合理(近邻法),预测值和实测值吻合程度高,可以满足刻蚀CR-39膜微图像和生物细胞辐照实验的要求.High resolution scattergrams of China map profile are etched on the CR-39 film within a small area of hundreds of microns × hundreds of microns by the AS-LIBB single proton microbeam, according to the coordinates of the standard images, which are acquired by the home-developed image-processing program. The testing results show that the single particle detection efficiency for this facility is over 98%, and the target-positioning accuracy is within 3 μm. Moreover, the near-path traversing algorithm for stage control is optimal for irradiating scattergrams of picture profile, and the dots on CR-39 film for the measured results and the expected values are quite identical. Therefore, this single particle irradiation system meets to the demands of etching micron-dimensional pictures on CR-39 film in dot manner with single particles and the needs of the biological cell irradiation experiments.
