The loss rate of ion beams and the non-neutral plasma in an axisymmetric magnetic mirror is investigated in the present paper. It is found that the loss rate increases as the mass of the ions increases for a ion beam confined in a magnetic mirror. Moreover, both the electron loss rate and the ion loss rate are obtained when a non-neutral plasma is confined in a magnetic mirror. It seems that both loss rate remain unchanged in the regime when the electron number density is less than that of the ions. In the other regime that the electron number density is much larger than that of the ion number, the ion loss rate increases with the increase of electron number density, while the electron loss rate decreases as the electron number density increases. This result may help us to devise a mirror to separate the different charged particles by confining these different particles in a magnetic mirror.

By using particle-in-cell(PIC) simulation method, the proton beam confinement in a magnetic mirror is investigated in the present paper. We define two physical quantities to describe the confinement effects of mirror for proton beam. One is loss rate χ=Nlost/N0, where Nlost is the number of leaked particles from the mirror and N0 is the number of initial particles. The other is confinement time τm. Dependences of loss rate and confinement time on the parameters of both magnetic mirror and proton beam is given. It is found that the larger the mirror ratio, the less the loss rate, and the longer the confinement time. The appropriate proton beam velocity and other parameters of the protons can significantly improve the confinement time of the mirror and the efficiency of confinement. [ABSTRACT FROM AUTHOR]
