基于日本小行星探测器隼鸟号的成功，ECR离子推进器μ10将安装在隼鸟号的后继者隼鸟2号上，计划在未来三年内实现商业化，用于地球静止卫星。为了在不进行重大设计变更的情况下尽可能增加μ10的推力，使用光纤探针进行了发光测量。探针给出了μ10的内部视图，发现波导中存在等离子体。由于等离子体的密度高于截止密度，干扰了微波的透射率，从而改变了推进剂的注入位置。除了推进剂注入位置的变化外，网格系统也得到了改进。这些改进使推力从8.0 mN增加到10.1 mN，比冲从3200秒减少到3160秒。
Based on the success of the Japanese asteroid explorer Hayabusa, the ECR ion thruster μ10 will be installed in Hayabusa's successor, Hayabusa-2, and is scheduled to be commercialized for use in geostationary satellites within the next three years. To increase the thrust force of the μ10 as much as possible without major design changes, luminescence measurements were conducted using an optical fiber probe. The probe gave an internal view of the μ10, and it was discovered that there was plasma in the waveguide. As the plasma, the density of which is higher than the cut-off density, interferes with the transmittance of microwaves, the propellant injection location was changed. In addition to the change in propellant injection location, the grid system was also refined. These improvements increased the thrust force from 8.0 mN to 10.1 mN with a decrease in specific impulse by 40 sec from 3200 sec to 3160 sec.
