    摘要: A vacuum ionization gauge (30) includes a cathode (31), an anode ring (33), a shield electrode (32), an ion educed electrode (34), a reflector (35) and a collector (36). The cathode is positioned corresponding to a first opening of the shield electrode, and the ion educed electrode is positioned corresponding to an opposite second opening of the shield electrode. An ion educed hole (341) is defined in a middle of the ion educed electrode. The reflector has a curving surface generally surrounding the second opening of the shield electrode. The collector is positioned at a center of the curving surface of the reflector and points toward the ion educed hole. The anode ring is positioned in the middle of the shield electrode. The vacuum ionization gauge is small volume and has low power consumption and improved sensitivity.

    摘要: An emitter includes an electrode, and a number of carbon nanotubes fixed on the electrode. The carbon nanotubes each have a first end and a second end. The first end is electrically connected to the substrate and the second end has a needle-shaped tip. Two second ends of carbon nanotubes have a larger distance therebetween than that of the first ends thereof, which is advantageous for a better screening affection. Moreover, the needle-shaped tip of the second ends of the carbon nanotube has a lower size and higher aspect ratio than the conventional carbon nanotube, which, therefore, is attributed to bear a larger emission current.

    摘要: A cold cathode device (20) includes a grid (24), a cold cathode (21) positioned under the grid, and a shield electrode (26) positioned above and parallel to the grid. A vacuum gauge includes a shell (32), a collector (39), an anode (38), and the cold cathode device of the present invention. The cold cathode device and the collector are positioned symmetrically relative to the anode. The collector, the grid and the cold cathode device are received in the shell. The shield electrode can shield an electric field of the grid for preventing from disturbing a symmetrical saddle field in the vacuum gauge. Electrons produced by the cold cathode device can obtain a long electron track because the electron vibration in the saddle field is symmetrical. Thus, the vacuum gauge has an improved sensitivity, and can be widely used to measure pressure in ultra-high and extremely high vacuum conditions.
