Preliminary investigation of quantum methodology in beam physics

Beam physics is a subject which studies the features of the beam particles transmission in electromagnetic field. It includes beam focusing, shaping and interaction with other particles. With the upgrade of beam energy and luminosity, some quantum aspects of beam particles, such as quantum effect of beam halo and spin effect on beam transport etc., seem important. Recently some accelerator physicists paid more attention on this field and named it as Quantum Beam Physics. In this paper, two different quantun methods are introduced and compared with the classical physical method.
