摘要
介绍了大型直线感应加速器机械轴精密对中安装方法和工艺。直线感应加速器由多个组元连接而成,总长几十m。采用激光跟踪仪并配以全站仪、水准仪进行准直测量,再用专门设计的高精度调节机构调节,可使机械轴的准直达到较高的精度。分析了准直安装各步骤能达到的精度,研究了几十m长机械轴准直控制测量网的建立和理论坐标值的修正。
Accurate mechanical axis alignment is a basic requirement for assembling a linear induction accelerator (LIA). The total length of an LIA is usually over thirty or fifty meters, and it consists of many induction cells. By using a laser tracker a new method of mechanical axis alignment for LIA is established to achieve the high accuracy. This paper introduces the method and gives implementation step and point position measure errors of the mechanical axis alignment. During the alignment process a 55 m-long alignment control survey net is built, and the theoretic revision of the coordinate of the control survey net is presented.
