为消除实验设备的影响,获得霍尔推力器羽流的真实特征信息,用在传统法拉第筒前加准直套的方法对推力器羽流进行了实验研究,得到了不同背景压力下离子电流密度的分布。结果表明：改进型法拉第筒能有效屏蔽电荷交换碰撞产生的低能离子,测得的离子电流密度分布更接近实际。

To eliminate the effect of the experiment device to gain the real characteristic information of the plume of the Hall thruster, the experiment was studied by using a collimator set before the tradition Faraday probe in this paper. The density distribution of the ion current under various background pressures was acquired. The results showed that the low-energy level ion caused by the exchanging impact of the charge would be isolated effectively by the improved Faraday probe. The density distribution of the ion current measured was more close to the real situation.
