摘要：

A plane polarized undulator does not have the ability to focus an electron beam in the undulating plane (X-Z plane) because the magnetic field decreases away from the X-axis. To focus in the bending plane, a quadrupole field must be added to the undulating field. This can be achieved using curved magnets or trapezoid-shaped magnets. In this article, we analyze a few magnet configurations which produce X-Z focusing. It has been found that semicircular magnets or trapezoid magnets having 1.2-degrees angle are suitable as focusing permanent magnet undulator.
