本文对日本原子能机构高崎TIARA加速器装置中与AVF回旋加速器（K = 110）相连的一种新型聚焦高能重离子微束系统进行了离子光学分析。从使用TRANSPORT代码计算到三阶项和用二次电子成像测量束分辨率来估计微束系统的聚焦性能。结果，在X和Y方向的FWHM中，最小束尺寸分别为0.56和0.62 μ m。高能重离子微束系统似乎已经建立了设计的计算与TRANSPORT程序，因为它被证实，计算结果是相当再现的测量结果。(C)2008爱思唯尔有限公司保留所有权利。
Ion optical analysis was made for a new focusing high-energy heavy ion microbeam system connected to the AVF cyclotron (K = 110) at the accelerator facility, TIARA of JAEA Takasaki. The focusing performance of the microbeam system was estimated from both the calculation up to third-order term using TRANSPORT code and the measurement of beam resolution with the secondary electron imaging, As a result, a minimum beam size was evaluated at 0.56 and 0.62 mu m in FWHM for the X and Y directions, respectively. The high-energy heavy ion microbeam system seemed to have been established as designed by the calculation with the TRANSPORT code, because it was confirmed that the calculation results was fairly reproduced by the measurement result.
