线性等离子体发生器是模拟当前和未来聚变反应堆分流体条件的一种经济有效的设备。规范B2.5-Eirene和EMC3-Eirene被广泛用于计划中的材料等离子体暴露实验（MPEX）的设计研究。利用B2.5-Eirene研究了气体加注和抽送位置、加热功率、装置长度、磁构型和输运模型对目标等离子体的影响。利用EMC3-Eirene计算了倾斜或垂直目标的效应，结果表明，将入射通量扩散到更大的区域会导致密度降低、温度升高和目标前方的离轴剖面峰值。模拟结果表明，在足够的加热功率下，MPEX可以达到与ITER分流器相似的目标等离子体条件。为了利用螺旋波加热线性装置的实验数据建立一个额外的基准，对MAGPIE实验进行了b2.5 - irene模拟。
Linear plasma generators are cost effective facilities to simulate divertor plasma conditions of present and future fusion reactors. The codes B2.5-Eirene and EMC3-Eirene were extensively used for design studies of the planned Material Plasma Exposure eXperiment (MPEX). Effects on the target plasma of the gas fueling and pumping locations, heating power, device length, magnetic configuration and transport model were studied with B2.5-Eirene. Effects of tilted or vertical targets were calculated with EMC3-Eirene and showed that spreading the incident flux over a larger area leads to lower density, higher temperature and off-axis profile peaking in front of the target. The simulations indicate that with sufficient heating power MPEX can reach target plasma conditions that are similar to those expected in the ITER divertor. B2.5-Eirene simulations of the MAGPIE experiment have been carried out in order to establish an additional benchmark with experimental data from a linear device with helicon wave heating.
