Title:
ELECTROMAGNET DEVICE, CONTROL METHOD FOR ELECTROMAGNET DEVICE, AND PARTICLE BEAM THERAPY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/209300
Kind Code:
A1
Abstract:
The present invention comprises: a plurality of coils 101, 102, 103, 104 arranged such that at least a part of the generated magnetic field overlaps; and a plurality of power supplies 41, 42, 43, 44. A calculation unit 621 and a supply control unit 622 of a power supply controller 620 adjust the amount of current that energizes the plurality of coils 101, 102, 103, 104, thereby reducing unnecessary error magnetic fields while maintaining the magnetic field strength required for beam transport. The present invention provides an electromagnet device for beam transport having a simple structure that maintains a highly accurate spatial distribution of a magnetic field.
