Role of Multipolar(4/6 or more polar) Permanent Magnet
Multipolar permanent magnet is used as one of the devices in accelerator. Per application of Loren magnetic principle, the electron accelerator focuses, accelerates and alters the moving directions of low-speed and scattered electrons shooting from the electron gun. Thus, the electron beam travels in an effective movement direction so that it's used to replace the electromagnetic accelerator whose polarization is not stable because of instable power current, voltage. The quadruple permanent magnet ensures the stability of polarization.
