Abstract
The detailed analyses of magnetic fields and undulator radiation spectra were performed on an undulator named Advanced Planar Polarized Light Emitter (APPLE). An APPLE, requiring no constraints in the electron orbit plane, consists of two pairs of planar permanent magnet arrays above and below the plane, and generates strong magnetic fields normal to the undulator axis on the electron orbit. Various magnetic fields produced with this undulator induce various electron motions such as vertically or horizontally sinusoidal motion and helical motion, thereby a linearly polarized radiation in the vertical or horizontal direction and also a circularly polarized radiation are generated. Magnetic field analyses of the undulator show that the phase difference between the horizontal field component B{sub x} and the vertical field component B{sub y} is always one fourth of undulator period regardless of the phase difference (D) of magnet array, and the multipole fields cause no serious problem if the magnet blocks are free from misalignment. Expected undulator radiation is calculated for an APPLE undulator with parameters assumed for the SPring-8 storage ring, and superior characteristics of the undulator radiation are represented.
