Title:
PARTICLE BEAM CONTROL SYSTEM AND PARTICLE BEAM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/238643
Kind Code:
A1
Abstract:
According to an embodiment, a particle beam control system (1) includes a control computer (11) that controls scanning electromagnets (5, 6), the control computer (11) being configured to: calculate, on the basis of a position of a particle beam (P) detected by a position monitoring unit (8), a centroid position as an actual irradiation position of the particle beam (P); calculate a deviation amount between a spot position as a design irradiation position of the scanning electromagnets (5, 6) and the centroid position; calculate a correction value for correcting the centroid position to the spot position on the basis of the deviation amount; store the correction value in a storage unit (18); and correct, on the basis of the correction value stored in the storage unit (18), a current value, which is designed to serve as the reference for supplying power from power sources (12, 13) to the scanning electromagnets (5, 6).
