通过ＭｏｎｔｅＣａｒｌｏ方法，模拟了磁场下矩形空心阴极放电中电子的运动及其产生非弹性碰撞情况，得到了终止条件下电子的能量分布、空间分布和离子的空间分布．磁场的引入改变了电子的行程和产生各种非弹性碰撞的次数与位置，影响了整个放电过程．电子的各种参数分布的差异，正是由少数非弹性碰撞决定的．通过模拟得到，选择恰当的磁场强度，可以获得高的电离度，适当的离子分布和电子分布．这对于更有效地利用空心阴极的优点，发展离子型激光器，可能具有一定意义．
By Monte Carlo method, we simulate the electron motion and the inelastic collision in rectangular hollow cathode discharge under magnetic field, and obtain the energy distribution, spatial distribution and ion spatial distribution of the electrons under the termination condition. The introduction of a magnetic field changes the number of electron strokes and the occurrence of a variety of inelastic collisions and locations, affecting the entire discharge process. Differences in the distribution of various parameters of the electron, it is determined by a few non-elastic collision. By simulation, the appropriate magnetic field strength can be selected to obtain high degree of ionization, appropriate ion distribution and electron distribution. This may be of interest to the development of ion lasers for the more efficient use of the hollow cathode.
