日本宇宙航空研究开发机构研究和开发了一种碳纳米管基场发射阴极，主要用于电动系绳推进的空间碎片清除系统。计划于2017年初进行在轨实验，以展示包括FEC在内的EDT技术。在为期一周的使命期间，FEC运行良好，没有出现任何严重故障。碳纳米管场致发射阴极（FEC）是日本宇宙航空研究开发机构研制的一种新型碳纳米管场致发射阴极，主要应用于电动系绳（EDT）推进的空间碎片清除系统。计划于2017年初进行在轨实验，以展示包括FEC在内的EDT技术。在为期一周的使命期间，FEC运行良好，没有出现任何严重故障。所获得的数据包括其对空间等离子体的电子发射能力和在低地球轨道上的耐久性，这些数据表明FEC在空间使用的前景。
A carbon nanotube-based field-emission cathode (FEC) has been researched and developed by the Japan Aerospace Exploration Agency mainly for space-debris removal systems with electrodynamic tether (EDT) propulsion. An in-orbit experiment to demonstrate the EDT technologies including the FEC was planned and conducted in early 2017. The FEC operated well without any critical trouble during the one-week mission period. The data obtained include its electron emission capability to space plasma and its durability in low Earth orbit, which suggest the prospect of using the FEC in space.A carbon nanotube-based field-emission cathode (FEC) has been researched and developed by the Japan Aerospace Exploration Agency mainly for space-debris removal systems with electrodynamic tether (EDT) propulsion.
