空间和宇航科学研究所正在筹划一项名为MUSE-C的小行星样本回收任务，其主要推进器是微波离子发动机系统。本文描述了用朗缪尔探头在微波放电室内用一台具有多种特性的7-mN/300W级微波放电离子对L进行的设计。放电室内的最大等离子体密度是4.2 GHz微波的截止密度的一个数量级，在有效产生等离子体的情况下，观察到环形的局域等离子体分布。
The Institute of Space and Astronautical Science is p lanning an asteroid sample return mission named MUSES-C, for which a microwave ion engine system is used as primary propulsion. This paper describes the design of a 7-mN/300W class microwave discharge ion e n g i n e , fo l lowed by an e v a l u a t i o n of p lasma characteristics inside the microwave discharge chamber using a Langmuir probe. The maximum, plasma density inside the discharge chamber was an order of the cut off density of the 4.2 GHz microwave, and a ring-shaped localized plasma distribution was observed in the case of efficient plasma production.
