摘要

中国散裂中子源（China Spallation Neutron Source，CSNS）漂移管加速器（Drift Tube Linac，DTL）是CSNS直线加速器段的末端，其准直精度直接关系到直线加速器的最终性能。由于其长度长、腔体和腔内漂移管数量多，准直精度要求高，因此准直难度极大。针对该问题，通过外符合全面测量对漂移管预准直后的精度进行检核，可知漂移管中心孔和端面的测量值在DTL腔的预准直精度达到±0.035 mm；采用大跨度、全覆盖的全面测量方法及平差在CSNS中的应用，实现直线隧道±0.03 mm和环隧道±0.04 mm的相对测量精度。提出了基于加速器准直的平滑计算及调整方法，实现DTL腔间的平滑调整，获得腔体±0.08 mm的隧道相对准直精度，漂移管±0.03 mm的腔内相对准直精度。

Abstract

Background

The drift tube Linac (DTL) is the end of the China Spallation Neutron Source (CSNS) Linac segment and its collimation accuracy is directly related to the final performance of the Linac. Because of its long length

large number of the cavity and drift tube

and high alignment accuracy requirement

it is extremely difficult to meet requirement.

Purpose

This study aims to explore high precision collimation method for DTL of CSNS and analyze the accuracy of drift tube pre-alignment.

Methods

Accuracy is verified by external coincidence measurement

and the pre-alignment accuracy of the center hole and the end face of the drift tube in the DTL cavity can reach 0.035 mm. The long-span

full coverage of the comprehensive measurement methods and adjustment in the CSNS application are employed to achieve high precision measurement.

Results

Experimental results showed that the relative measurement accuracy in straight tunnel was 0.03 mm and 0.04 mm in ring tunnel.

Conclusion

A smooth calculation and adjustment method based on accelerator alignment proposed in this paper can be used to obtain the cavity's relative collimator precision of 0.08 mm and the drifting tubes' relative alignment accuracy of 0.03 mm

and thus the smooth adjustment between DTL cavities can be realized.
