The particle confinement has been studied by Monte-Carlo simulation in the intermediate regime between the collisional and collisionless regimes for the mirrors with space-varing magnetic fields, for example, LAMEX and parabolic magnetic field profiles. The particle confinement time in the intermediate regime is longer than the extrapolation values based on the formulas in other two regimes, and proportional to the mirror ratio. The density profiles have been obtained as self-consistent solutions from the simulation....

The particle confinement has been studied by Monte-Carlo simulation in the intermediate regime between the collisional and collisionless regimes for the mirrors with space-varing magnetic fields, for example, LAMEX and parabolic magnetic field profiles. The particle confinement time in the intermediate regime is longer than the extrapolation values based on the formulas in other two regimes, and proportional to the mirror ratio. The density profiles have been obtained as self-consistent solutions from the simulation. The dependence of the density profile on the plasma parameters are discussed.

本文在碰撞区和无碰撞区之间的过渡区,就LAMEX和抛物线轮廓两种空间变化磁场磁镜,用Monte-Carlo模拟研究了粒子约束问题。在过渡区,粒子约束时间高于其它两区公式的外推值,并与磁镜比成正比关系。这一模拟还用自洽解的方法得到了密度轮廓,并研究了这一轮廓和等离子体参数的关系。

According to the characteristics of No-Hit-Zone (NHZ) hopping code, a multi-access quasi-synchronous scheme based on NHZ hopping code for frequency hopping communication system was proposed. Simulation results prove that the scheme assured the frequency hopping system to work within NHZ hopping code. It decreases the multi-access interference and improves the integral bit error rate performance of the system, and is suitable for multi-user frequency hopping system.
