Title: Deflecting electromagnet for particle accelerator
Inventor: NAKAGORI TADASHIGE
IPC: H05H7/04
Filed: 1990-04-09
Abstract: PURPOSE:To reduce the effective width of the deflecting electromagnet and to reduce its size providing correcting coils which are fed with currents according to the intensity of a magnetic field on the incidence side and projection side on the axis of a charged particle beam, and holding the effective length of the magnetic field constant. CONSTITUTION:The correcting coils 3 and 4 which correct the magnetic flux distribution of charged particles are provided at a magnetic pole end part 1A that the charge particles enter and exit from. The coils 3 and 4 are fed with the currents corresponding to the intensity of the magnetic field and operate without varying in magnetic field effective length even if the intensity of the high magnetic field varies. Namely, as the magnetic field is intensified, the magnetic flux distribution in the magnetic field end part 1A decreases, but the coils 3 and 4 compensate the magnetic field so that the value obtained by integrating the intensity of the magnetic field on the track of the particles with the distance of the track corrected to a constant value. Therefore, the track of a beam does not vary from a low magnetic field to a high magnetic field and the beam passes the same place, so the deflecting electromagnets are reducible in size and when the magnets are applied to a synchrotron accelerator, frequency modulation is eliminated to stably accelerate the beam.
