【摘要】：武威医用重离子加速器是目前世界上最紧凑的重离子加速器治癌装置,同步环周长小至56.1 m,其中很多关键元件的安装定位精度要求达到亚毫米量级,四极透镜的定位精度要求0.1 mm。结合激光跟踪仪的特点和测量学知识通过三维控制网及多重坐标系的转换,探索了一种在元件自身坐标系下调节准直的方法,提高了准直安装的工作效率,使得最后所有的元件安装各向误差均控制在0.1 mm以内,其结果优于该装置的精度要求,使得同步环在短时间内顺利调束成功,从而验证了同步环准直测量的可靠性与准确性。
[Abstract]:Wuwei Medical heavy Ion Accelerator is the most compact heavy ion accelerator for cancer treatment in the world at present. The circumference of the synchronous ring is as small as 56.1 m.The installation accuracy of many of the key components is in the order of sub-millimeter. The positioning accuracy of quadrupole lens should be 0.1 mm. Based on the characteristics of laser tracker and the knowledge of measurement, a method of adjusting collimation in the coordinate system of elements is explored through the conversion of 3D control network and multi-coordinate system, and the working efficiency of collimating installation is improved. Finally, the errors of all the components are controlled within 0.1 mm, the result is superior to the precision requirement of the device, and the synchronous ring is successfully adjusted in a short time, which verifies the reliability and accuracy of the collimation measurement of the synchronous ring.
