    摘要: An electron beam tube includes an electron gun 1 included within a vacuum envelope defined partly by a ceramic cylinder 6. The ceramic cylinder 6 includes straight sided portions 7 and 8 with an intervening conical section 9 between them. The straight sided portions 7 and 8 form part of two r.f. chokes, being metallised on their inner and outer surfaces and forming a connection with a cavity forming part 15.
