Calibration of the tracker’s angle measurement error for linac control network

  • 摘要: 根据关键设备在直线加速器隧道内的布局,控制网布设在隧道地面和墙面。跟踪仪是直线加速器控制网测量的主要仪器,跟踪仪的测角误差是影响设备精度的关键因素。根据隧道墙面和地面网点的布局以及跟踪仪测量方案,对跟踪仪所有测量状态下的水平角和垂直角进行分解;然后通过高精度三坐标测量仪和跟踪仪联动测试,对分解后的角度进行高精度求解,解算值用于修正跟踪仪的实测角度。结果表明,不管是哪种测量状态,跟踪仪实测角度值均大于解算值;地面网点垂直角和水平角的偏差与跟踪仪的标称精度基本相当;墙面点水平角超过15°时,测角误差随着角度的增加而增大,在隧道控制网测量时需要对墙面点水平角进行修正。
