摘要
Abstract
In the rapid cycling synchrotron of China Spallation Neutron Source (CSNS/RCS) ,the 48 quadrupole magnets are divided into four types according to their aper‐tures .Four types of quadrupole prototype magnets were manufactured and measured using a harmonic coil system . The first magnetic field measurement results at DC current show that some multipole magnetic field contents are larger than those of the requirement and should be reduced . T he magnetic field harmonic adjustment scheme was determined and carried out based on the 3D magnetic field simulation with OPERA . After the correction ,all the magnetic harmonics of the quadrupole prototype magnets are within the requirements .关键词
