Japan, Sept. 18 -- HITACHI LTD has got intellectual property rights for 'ACCELERATOR ELECTROMAGNET, ACCELERATOR, AND PARTICLE BEAM THERAPY SYSTEM.' Other related details are as follows:
Application Number: JP,2022-200988
Category (FI): H05H13/04@G,A61N5/10@H,H05H7/10
Stage: PROBLEM TO BE SOLVED: To provide an accelerator electromagnet that can reduce the deviation between the trajectory of a high-energy charged particle and the trajectory of a low-energy charged particle compared to the conventional art, and an accelerator and a particle beam therapy system including the same.SOLUTION: An accelerator electromagnet includes a return yoke 42 and a pair of magnetic poles 41 fixed to the return yoke 42, and a return yoke hole 43 is formed in the return yoke 42 in a region that intersects with the emission trajectory of a charged particle beam, and the return yoke hole 43 is configured such that its shape differs depending on the energy of the passing charged particle beam, thereby adjusting the magnetic field distribution therein.SELECTED DRAWING: Figure 3 (Grant)
