  • Publication number: 20200352018
    Abstract: An undulator is adapted to a synchrotron storage ring or free electron lasers (FEL), especially to an undulator capable of switching polarization mode rapidly. In comparison with the EPU (elliptically polarized undulator) of APPLE II (Advanced Planar Polarized Light Emitter II) which conceived by Dr. S. Sasaki, the provided undulator does not use mechanical transmission mechanisms to drive the four magnetic pole arrays composed of permanent magnets. Hence, the polarization mode can be switched rapidly. Moreover, a polarization method of electron beam is also provided.
