摘      要：Background Heavy ion medical machine(HIMM)is built by the Institute of Modern Physics,Chinese Academy of Sciences,with a high-energy beam transport line with a height of 18 m,and its complex space mounting structure increases the difficulty of installation and *** The aim of this paper is to provide methods to install all accelerator components efficiently and to ensure that the alignment accuracies of all installed components are within the designed *** We accomplished the fiducialization and pre-alignment of complex modules by combining the laser tracker and the alignment *** analyzing various elements that affect the accuracy of alignment,a method of alignment for high-energy beam transport line was proposed based on high-precision three-dimensional control *** All components have been installed and aligned in a short time,alignment position accuracy of magnets is less than 0.1 mm,and the treatment components alignment accuracy is no more than 0.4 *** On the basis of error analysis,all alignment results are better than the required precisions,and all of these guaranteed the successful operation of HIMM.
