我们已经开发出一种新的静电分析仪，使中等能量（10200 keV闪烁）等离子体粒子测量与全立体角覆盖。实验模型的设计实现了在±5 kV高压下最大测量能量为200 keV的闪烁。试验模型分析仪的实验结果表明，其性能与数值模拟结果一致。测试模型设计非常适合与质量分析单元组合，而我们的新设计也可以应用于中能电子测量。具有这种新设计的中能离子/电子传感器肯定会在即将进行的空间飞行任务中受到重视，这些任务将观测内磁层或重连区等区域的热/高能等离子体结构。
We have developed a new electrostatic analyzer which enables medium energy (≲200 keV∕q) plasma particle measurements with full solid angle coverage. The design of the test model realizes the uppermost measurement energy of ∼200 keV∕q with applied high voltages of ±5 kV. Laboratory experiments with the test model analyzer show that its performance agrees with numerical simulations. The test model design is well suited for combination with a mass analysis unit, while our new design can also be applied to medium energy electron measurements. Medium energy ion/electron sensors with this new design will surely be appreciated for upcoming space missions that will observe hot/energetic plasma structures in the regions such as the inner magnetosphere or reconnection region.
