Abstract :
In this paper, an open type of MSR combined with cancelling coils is investigated. The optimal position of the cancelling coil from the standpoints of the leakage flux density outside the room and the required current is determined using 3-D magnetic field analysis with the finite element method. Moreover, the structure for maximizing the opening of a MSR is proposed.
