摘　　要：为了延长靶的使用寿命以及提高质子束流的利用效率,中国拟建造加速器驱动次临界系统(ADS)。质子直线加速器的中能束流输运线共分为MEBT1和MEBT2两部分。这两部分共计20块常规磁铁,其中,MEBT1含6块四极磁铁,MEBT2含6块四极磁铁、4块阶梯场磁铁、3块校正磁铁和1块二极磁铁。霍尔测量平台目前已完成MEBT1四极磁铁和MEBT2四极磁铁和校正磁铁的测量。本文通过对这些磁铁的积分场分布、积分励磁分布、横向场分布、励磁效率等测量结果的分析,验证了常规磁铁的各项指标,所有常规磁铁的测量结果均达到了设计要求。In order to prolong the time of the target and improve the efficiency of the proton beam, China intends to build an accelerator driven sub-critical system （ADS）. Proton＇s energy beam transport line is divided into two parts MEBT1 and MEBT2. The two parts total 20 conventional magnets. MEBT1 contains six quadrupole magnets; MEBT2 contains six quadrupole magnets, four stepped field magnets, three correction magnets and a dipole magnet. Holzer measuring platform has completed MEBT1 qua- drupole magnet, MEBT2 quadrupole magnet and correction magnet. Based on analyzing the measured results （including the integration field distribution, integrated field distri- bution, horizontal distribution, excitation efficiency） of these magnets and properly val- idated indicators of conventional magnets, the results of all conventional magnets meet the design requirements.
