摘要：

Metal-tip-array　field　emission　cathodes　with　non-integrated　mesh　gates　are　proposed　to　be　the　electron　sources　for　X-ray　tubes.　The　cathodes　theoretically　have　better　emission　uniformity　than　carbon　nanotubes　(CNTs)　cathodes　which　are　most　used　in　field　emission　X-ray　tubes　and　work　more　stable　than　cathodes　with　near-integrated　gate.　The　cathodes　are　fabricated　mainly　based　on　Spindt　cathodes　process　in　present　and　the　process　is　expected　to　be　simplified　in　further　research.　©　2017　IEEE.
