Abstract
This chapter is devoted to the study of field electron (FEE) and explosive electron (EEE) emissions from carbon nanoclusters and considers the prospects of their use in the development and production of portable X-ray sources. It was found earlier that the macroscopic fields that are necessary to excite the FEE and the EEE from nanoclusters are 2–3 orders of magnitude less than those needed for conventional metal and semiconductor emitters. Recent results, related to the study of portable X-ray sources operating on the basis of explosive electron emission, are highlighted. Particular portable X-ray devices, with an explosive emission cathode made from carbon nanoclusters, are described.
