Abstract:
A flat microtip display screen including a cathode provided with active areas of electron emission microtips; a cathodoluminescent anode provided, at least in front of the active microtip areas, with active areas of phosphor elements; a main grid of extraction of electrons emitted by the active microtips towards the phosphor elements; and on the cathode side, at least one sacrificial area of microtips adapted to being addressed, outside screen operation periods and independently from the active areas.
Abstract:
An ultra-high vacuum (UHV) system includes a UHV cell and an ion pump to maintain the UHV in the UHV cell. The ion pump has a GCC (glass, ceramic, or crystalline) housing. An interior wall of the ion-pump housing serves as an anode or bears a coating that serves as an anode. At least one cathode is disposed with respect to the housing so that it can cooperate with the anode to form an electric field for establishing a Penning trap. The GCC housing defines a flow channel that extends radially through the anode so that a molecule can flow directly into the most ionizing region of a Penning trap.
Abstract:
A sputter ion pump comprises a metal pump container. In the pump container are arranged a cathode and an anode opposed to each other in the pump container and a permanent magnet situated between the cathode and the inner surface of the pump container. After locating the anode, cathode, and magnetic material in the pump container, the magnetic material is magnetized from outside the pump container, thereby forming the permanent magnet.

Abstract:
An ion drag vacuum pump is installed in a body, one side of which is connected to and in communication with a sealed chamber. An ion generating device and a positive ion dragging device for dragging positive ions generated by the ion generating device to exhaust gases located near the ions by speeding up the ions is disposed in the body. The positive ions are neutralized by a positive ion neutralizing device. The ion generating device includes a corona electrode as a corona discharger to which a positive voltage is applied, a metal plate as a DC glow discharger to which a positive DC voltage is applied, or a first RF electrode and a second RF electrode to which RF power is applied. The ion dragging device includes a target electrode or a first and a second grids to which a positive and a negative voltage are respectively applied. The ion neutralizing device includes a grounded baffle plate.
