Abstract: An ionization vacuum gauge includes a linear cathode, an anode, and an ion collector. The linear cathode, the anode, and the ion collector are concentrically aligned and arranged from center to outer, in that order. The linear cathode includes a linear base and a field emission film deposited coating on the linear base. The ionization vacuum gauge with low power consumption can be used in a high vacuum system and/or some special vacuum system that is sensitive to heat and light. Such a gauge can be used to determine, simply yet accurately, pressures at relatively high vacuum levels.

Abstract: A field emission device (6), in accordance with a preferred embodiment, includes a cathode electrode (61), a gate electrode (64), a separator (62), and a number of emissive units (63) composed of an emissive material. The separator includes an insulating portion (621) and a number of conductive portions (622). The insulating portion of the separator is configured between the cathode electrode and the gate electrode for insulating the cathode electrode from the gate electrode. The emissive units are configured on the separator at positions proximate to two sides of the gate electrode. The emissive units are in connection with the cathode electrode via the conductive portions respectively. The emissive units are distributed on the separator adjacent to two sides of the gate electrode, which promotes an ability of emitting electrons from the emissive material and the emitted electrons to be guided by the gate electrode toward a smaller spot they bombard.

Abstract: A light source apparatus (8) includes a rear plate (80), a front plate formed with an anode layer (82), and a cathode (81) interposed therebetween. The cathode includes a plurality of electrically conductive carriers (812) and a plurality of field emitters (816) formed thereon. The field emitters are uniformly distributed on anode-facing surfaces of the conductive carriers. Preferably, the field emitters extend radially outwardly from the corresponding conductive carriers. The conductive carriers are parallel with each other, and are located substantially on a common plane. Each of the conductive carriers can be connected with a pulling device arranged at least one end thereof, and an example of the pulling device is a spring. The conductive carriers may be cylindrical, prism-shaped or polyhedral.
