Abstract (en)
[origin: US2002003395A1] In order to improve the definition and the breakdown behavior in a tube neck (16) that includes an anode cylinder (20) and a focusing cylinder (19), the tube neck (16) is made of a non-conductive material, particularly a ceramic. The inner surface of the anode cylinder (20) and the inner surface and the outer surface of the focusing cylinder (19) are coated with an electrically conductive material (21).
