Abstract
A saddle type dipole coil comprises a pair of elongated ring shaped upper and lower coil layers each having an assembly of coil conductors of series-connected turns. The upper and lower coil layers are opposed each other and disposed on the outer surface of a duct. The end portions of the upper and lower coil layers positioned in a range of a predetermined width are so extended by a predetermined length in the longitudinal direction that the integral value of only sextupole components of a magnetic field is minimized or set nearly zero among the entire multi-pole components of the magnetic field, thereby enabling to make a synchrotron radiation ray generating device with good efficiency of accelerating particles.
