Adjustment method of control network for alignment in CSNS

Control network is the reference of equipment installation and alignment, so the adjustment processing of control network is very important. In this paper, the data processing methods of separate plane and elevation adjustment and three-dimensional adjustment were studied in LINAC of China Spallation Neutron Source. Meanwhile, to make the data processing more simple and convenient, SA software was introduced to realize three-dimensional adjustment with the gravity orientation constrained. Through the comparison of different software and different data processing methods, correctness of the data processing of the control network is verified. Finally, the accuracy of the 200 m linear control network was better than 0.2 mm, which provides guidance for data processing of control network for alignment.
