Currently, the properties of cathodes based on various carbon materials, including carbon nanotubes, are being actively studied. Great hopes are placed on cathodes made of these materials. However, until now, the requirements for the stability of the emission current and the uniformity of the field emission image have hindered the creation and wide use of devices based on them. In this work, it was proposed to investigate the possibility of using multi-emitter carbon nanotube cathodes for the development of field cathodes. To do this, we studied the field emission properties of multi-emitter cathodes based on filaments of multi-walled carbon nanotubes. As a result of the experiments, the results of measuring the current-voltage characteristic for systems with such cathodes were obtained. The results of this work can be used in the design of emission electronics devices, in particular, cathodoluminescent light sources.
