    Abstract: Disclosed is an ion gate for a dual IMS and method. The ion gate includes an ion source, a first gate electrode placed on one side of the ion source, a second gate electrode placed on the other side of the ion source, a third gate electrode placed on the side of the first gate electrode away from the ion source, a fourth gate electrode placed on the side of the second gate electrode away from the ion source, wherein during the ion storage, the potential at the position on the tube axis of the ion gate corresponding to the first gate electrode is different from the potentials at the positions on the tube axis corresponding to the ion source and the third gate electrode, and the potential at the position on the tube axis corresponding to the second gate electrode is different from the potentials at the positions on the tube axis corresponding to the ion source and the fourth gate electrode. According to the present invention, after sample gas enters the ion gates, charge exchange with reaction ions occurs between the first gate electrode and the second electrode, and positive and negative ions are continuously stored into the storage regions for the positive and negative ions. This leads to an improvement of utility rate of ions. Then, the ions are educed in a step-wise manner from the storage regions for the positive and negative ions by a simple control of a combination of the electrodes.

    Abstract: The invention describes a particle source in which energy selection occurs. The energy selection occurs by sending a beam of electrically charged particles 103 eccentrically through a lens 107. As a result of this, energy dispersion will occur in an image formed by the lens. By projecting this image onto a slit 109 in an energy selecting diaphragm 108, it is possible to allow only particles in a limited portion of the energy spectrum to pass. Consequently, the passed beam 113 will have a reduced energy spread. Deflection unit 112 deflects the beam to the optical axis 101. One can also elect to deflect a beam 105 going through the middle of the lens toward the optical axis and having, for example, greater current.The energy dispersed spot is imaged on the slit by a deflector 111. When positioning the energy dispersed spot on the slit, central beam 105 is deflected from the axis to such an extent that it is stopped by the energy selecting diaphragm. Hereby reflections and contamination resulting from this beam in the region after the diaphragm are avoided. Also electron-electron interaction resulting from the electrons from the central beam interacting with the energy filtered beam in the area of deflector 112 is avoided.

    Abstract translation: 本发明描述了发生能量选择的粒子源。 通过透过透镜107偏心地发送带电粒子103的束来进行能量选择。结果，由透镜形成的图像中会发生能量分散。 通过将该图像投影到能量选择膜108中的狭缝109上，可以仅允许能谱范围的有限部分中的粒子通过。 因此，通过的梁113将具有减小的能量扩展。 偏转单元112将光束偏转到光轴101.也可以选择将穿过透镜中间的光束105偏转到光轴并具有例如更大的电流。 能量分散点通过偏转器111在狭缝上成像。当将能量分散光斑定位在狭缝上时，中心光束105从轴线偏转到被能量选择光阑停止的程度。 因此避免了在隔膜之后的区域中由该光束产生的反射和污染。 避免了在偏转器112的区域中与来自中心光束的电子与能量过滤光束相互作用的电子 - 电子相互作用。

    Abstract: Described is a micro-fabricated charged particle emission device including a substrate and a plurality of charged particle emission sites formed in the substrate. A path extends between each emission site and a source of liquid metal. Each path is coated with a wetting layer of non-oxidizing metal for wetting the liquid metal. Exemplary non-oxidizing metals that may be used to provide the wetting layer include gold and platinum. The wetting layer is sufficiently thin such that some liquid metal is able to flow to each emission site despite any chemical interaction between the liquid metal and the non-oxidizing metal of the wetting layer.

    Abstract: In certain example embodiments of this invention, there is provide an ion source including an anode and a cathode. In certain example embodiments, the cathode does not overhang over the anode, or vice versa. Since no, or fewer, areas of overhang are provided between the anode and cathode, there is less undesirable build-up on the anode and/or cathode during operation of the ion source so that the source can run more efficiently. Moreover, in certain example embodiments, an insulator such as a ceramic or the like is provided between the anode and cathode.

    Abstract: The present invention provides a source of plurality of radiation types using a single source that is made of ferroelectric material in the form of a cathode. The generated radiation types consist of ion and electron beams, X-ray, visible light and ultraviolet radiation. These types allow testing the surface and bulk of the same medium while placed in the same location and are providing confirmation and independent measurements of the material properties. The cathode is made with a continuous electrode on one side and a grid shape electrode on the other. This cathode is supported with fixtures that are used to produce various radiation types. Also, control elements are used to define the shape and directivity of the emitted beam. The present invention eliminates the need for plurality of instruments for obtaining required properties of test materials covering both the surface and the bulk of the test medium. The disclosed source emits multiple types of charged particles and radiation using switchable electromechanical elements. The source performance is enhanced by use of a ferroelectric wafer with a high dielectric constant, and the control of the driving pulse shape. A set of stacks and arrays of multiplexed ferroelectric cathode wafers are used to offer various options in the design of the Ferrosource.

    Abstract: A discharge device for operation in a gas at a prescribed pressure includes a cathode having a plurality of micro hollows therein, and an anode spaced from the cathode. Each of the micro hollows has dimensions selected to produce a micro hollow discharge at the prescribed pressure. Preferably, each of the micro hollows has a cross-sectional dimension that is on the order of the mean free path of electrons in the gas. Electrical energy is coupled to the cathode and the anode at a voltage and current for producing micro hollow discharges in each of the micro hollows in the cathode. The discharge device may include a discharge chamber for maintaining the prescribed pressure. A dielectric layer may be disposed on the cathode when the spacing between the cathode and the anode is greater than about the mean free path of electrons in the gas. Applications of the discharge device include fluorescent lamps, excimer lamps, flat fluorescent light sources, miniature gas lasers, electron sources and ion sources.
