The paper investigates the creation of light sources of a new generation based on the phenomenon of field emission from a cathode with a large number of emission centers. As a cathode, carbon materials with a large number of emission centers are used - multi-emitter cathodes. The aim of this work was to study a multi-cathode system consisting of multi-emitter field emission cathodes. As a result, a multi-cathode structure of multi-emitter cathodes was developed and created. During the experiments, the hypothesis with the additivity of emission patterns for several cathodes was tested and successfully confirmed. The results of the work can be applied in the design of a multi-cathode structure, which can be used in lamps for various purposes.
