Vacuum plasma fast aging with self-adjusted effect for SCFE under high current electron beam

At present, various carbon field electron emitters (CFE) have already got extensive applications, related researches got in depth day by day. In the field of application of carbon field electron emitter, once we need to consider the operation environment of an application, according to the feature of electron beam, we can divided all the applications into two fields: application of the low current electron beam, and the application of the high current electron beam. In basic, the CFE is getting to appear its advantages on all application fields. This paper will study the physical mechanics of aging process happened in vacuum gap and the bulk of SCFE, according to relative reports and knowledge accumulated about over past 40 years, introduce our experiments and internal factors inside the SCFE in detail.
