Abstract：
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 3mm. 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.
