摘要

SSC-Linac RFQ (Separated Sector Cyclotron Linac Radio Frequency Quadrupolec)是中国科学院近代物理研究所和北京大学共同研制的国内首台高电荷态强流重离子连续波四杆型加速器，机械加工的高精度是RFQ能否顺利出束的关键步骤之一。为了检测其机械形位公差，采用了激光跟踪仪和关节测量臂合理组合应用的测量新方法，使两种高精度的测量仪器能扬长避短，克服了大尺度工件形位公差传统测量方法的不足，使其在测量过程中发挥其最优的使用性和操作性，有效地提高了工作效率，从而保证RFQ高精度的测量结果。

Abstract

Background: Separated Sector Cyclotron Linac Radio Frequency Quadrupolec (SSC-Linac RFQ) is the first domestic high charge state accelerator developed together by Institute of Modern Physical

Chinese Academy of Sciences and Peking University. High precision mechanical control is one of the key indicators for RFQ to obtain needful beam. Purpose: The aim is to detect the mechanical tolerances of form and position of large scale workpiece shape. Methods: The new survey method that combining laser tracker and articulated arm are adopted to overcome the shortcomings of measuring the shape and position tolerances of large-scale workpiece. Results: The measuring efficiency was effectively improved

which ensured the high precision RFQ measurement results. Conclusion: SSC-Linac RFQ beam was successfully obtained on April 4

2014

with the output energy of 141.9 keV?u?1

current 149.5 ?A

and the transmission efficiency higher than 80%. The combined application of measurement using laser tracker and a measuring arm ensures the accuracy of mechanical measurement of SSC-Linac small line in RFQ. Abstract
