Abstract: Within an ion pump, accelerated ions leave the center portion of an anode tube due to the anode tube symmetry and the generally symmetrical electric fields present. The apparent symmetry within the anode tube may be altered by making the anode tube longitudinally segmented and applying independent voltages to each segment. The voltages on two adjacent segments may be time varying at different rates to achieve a rasterizing process. In various embodiments, one or more wire internal to the anode structure and having a time-varying electric potential may alter the trajectory of the ions leaving the anode tube, as may the shape of the anode near the ends of the anode tube.

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: 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.

Abstract: An electrostatic pump includes two electrodes, which are spaced apart essentially in the pump flow direction and which are adapted to have applied thereto a potential for injecting an ion current flowing between the two electrodes. For further microminiaturization of the pump, the pump includes two semiconductor components, which are arranged one on top of the other in the pump flow direction and which are so structured that the electrodes form an integral constituent part of the semiconductor components.

Abstract: A FLUERIC DEVICE FOR CONVERTING ELECTRICAL ENERGY INTO FLUID ENERGY AND VICE VERSA. THE BASIC DEVICE IS OF A LAMINATE STRUCTURE COMPRISED OF TWO ELECTRICALLY CONDUCTIVE, CHANNELLED ELECTRODE MEMBERS, AN EMITTER AND A RECEIVER, WHICH ARE SPACED A GIVEN DISTANCE FROM EACH OTHER AND JOINED BETWEEN LAYERS OF ELECTRICALLY INSULATING MATERIAL. THE CHANNELS OF THE EMITTER AND RECEIVER ARE ALIGNED SO AS TO FORM A FLOW PASSAGE THROUGH THE DEVICE.

A DIRECT CURRENT ELECTRIC POWER SUPPLY IS IMPRESSED BETWEEN THE EMITTER AND RECEIVER TO CAUSE A FLOW OF IONS FROM THE EMITTER TO THE RECEIVER WHICH CAUSES FLUID TO BE PULLED FROM AN INLET THROUGH THE CHANNELS OF THE EMITTER AND RECEIVER AND OUT AN EXIT OF THE DEVICE.
