本文简述了六端口自动反射计的原理,介绍了我们研制的自动反射计和用它来调配北京正负电子对撞机的直线加速器盘荷波导的结果。实验表明,相位调谐精度远优于测量线法,误差很容易控制在±1.5°范围内,调配速度比用测量线法提高十倍以上。全部结果可由计算机存盘保存,并由打印机,绘图机输出。 This paper briefly describes the principle of six-port automatic reflectometer, introduces the automatic reflectometer we developed and uses it to deploy the linear accelerator dish waveguide of the BSE. Experiments show that the phase tuning accuracy is far better than the measurement line method, the error is easily controlled within ± 1.5 °, deployment speed than the measured line method to improve more than ten times. All the results can be saved by computer save, and by the printer, plotter output.
