摘 要：Objective:This study is aimed at measuring the ripple of magnetic power supply of BEPCII and checking its effect to beam *** and methods:A sensor made of printed circuit board coils is designed and *** sensor was inserted into a good area region of the magnetic field with the surface perpendicular to the field force *** change of the magnetic field would be detected according to Faraday’s ***:The experiment result indicates that the timedependent ripple of the magnetic field is in the magnitude of ***:Such a small effect of the time-dependent ripplecan be negligibleto beam energy.
