摘要: 微束辐照装置是将辐照样品的束斑缩小到μm量级, 能够对辐照粒子进行准确定位和精确计数的实验平台, 是开展辐照材料学、 辐照生物学、 辐照生物医学和微加工的有力工具。 μm量级的束流对设备的准直安装也提出了极高的要求, 对于HIRFL系统微束线上的二极磁铁, 由于其所在位置的空间相当狭小, 使得设计就位时磁铁的位置及角度与地面做基准时的不同, 这给安装准直工作带来了挑战。 通过引入变化的基准坐标值的办法, 有效解决了这一难题, 使全部磁铁安装误差都控制在了要求的公差范围之内。 Microbeam irradiation facility is a experiment platform, which can reduce the beamspot on the irradiated sample to micrometer level, and can accurately locate and count the radioactive particles. It is a powerful research tool for the irradiation material science, irradiation biology, irradiation biomedicine and micro mechanical machining. The microbeam irradiation facility requires the precise work for installation and alignment. These conditions make magnet’s change for directions and positions because the location space of dipole magnets in microbeam line of HIRFL(Heavy Ion Research Facility in Lanzhou) is very small. It is a challenge for the installatior and alignment work of magnets. It was solved by transforming coordinates of benchmarks of magnets, which controlled the error of magnet setup within error tolerance range.
