Development of a Permanent Magnet Magnetic System for an Energy-Saving Synchrotron Radiation Source

Abstract

New technologies can be used to further improve the parameters of synchrotron radiation sources. One of them is the use of permanent magnets when creating elements of the magnetic storage system. This will help eliminate the influence of power supply instability and vibrations caused by the operation of the cooling system on the stability of the electron beam position. In addition, the use of permanent magnets will make it possible to increase the aperture of the vacuum chamber and, thus, simplify the vacuum and injection systems of the storage device, as well as increase the threshold instability currents. This work is devoted to the development of two bending magnets, focusing and defocusing, which make up the regular part of the magnetic system of an energy-saving compact synchrotron radiation source. The design and results of magnetic field modeling are presented.
