Abstract: [Object] To provide a tether that is automatically deformed from a deployment state in case of cutting or the like.[Solving Means] A tether 10 is a net that kinks and is automatically deformed upon tension release. The tether 10 has a length of several kilometers to several tens of kilometers upon deployment and is capable of shrinking to have a length of approximately several tens of meters to several hundreds of meters by kinking and automatically being deformed when the tension is released because of cutting or the like.

Abstract: [Object] To provide an electron source that is lightweight, simple in configuration, and capable of suppressing characteristic degradation or recovering characteristics without causing an increase in power consumption.
[Solving Means] A CNT electron source includes: a CNT emitter 32 for emitting electrons; a gate electrode 33 for extracting electrons from the CNT emitter 32; and a gate power supply connection switching relay 37a and a CNT emitter grounding switching relay 37b that cause the gate electrode 33 to emit electrons to irradiate the CNT emitter with electrons.
