摘　　要：This paper presents the model cavity tune and cold test of an S-band 2MeV on-axis coupling SW accelerator. The measurement of the model cavity's frequency,degree of coupling,Q value and on-axis field distribution are described in detail.In addition,the results of cavity tune and cold test of the accelerating tube are given.The frequency consistency of the accelerator is within±0.3MHz,the coupling degree in the supersaturation state 1.14,the quality factor of the accelerator 12000±200,and the field distribution ratio 1:2.2:2.All the results observed show that the accelerator satisfies the physics design with microwave debugging.介绍了用于工业CT的S波段2MeV驻波电子直线加速管的微波冷测及调整,并详细描述了加速管频率的测量与调谐,加速管与矩形波导匹配,加速管品质因数及加速管整管场分布的测量,给出了加速管微波调试及调整的结果.结果如下:加速管的频率一致性达到±0.3MHz以内,过饱和状态下的耦合度为1.14,加速管单腔的品质因数约为12000±200,场分布的比值1:2.2:2.结果表明微波调试满足物理设计的要求.
