摘要： An electron accelerator (10) includes a vacuum chamber (46) having an electron beam exit window (24). An electron generator (31) is positioned within the vacuum chamber for generating electrons. A housing (30) surrounds the electron generator and has a first series of openings (34) formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window. The housing also has a second series and third series of openings (35) formed in the housing on opposite sides of the electron generator for causing electrons to be uniformly distributed across the electron beam by flattening electrical field lines between the electron generator and the exit window.

摘要： 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.
摘要翻译：本发明描述了发生能量选择的粒子源。能量选择通过透过透镜107偏心地发送一束带电粒子103来发生。其结果是，能量分散将发生在由透镜形成的图像中。通过将该图像投影到能量选择膜片108中的狭缝109上，可以仅允许能量谱的有限部分中的粒子通过。结果，通过的光束113将具有降低的能量分布。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朝向光轴偏转并且具有例如更大的电流。能量色散斑点由偏转器111在狭缝上成像。当将能量色散斑点定位在狭缝上时，中心光束105从轴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射束引起的反射和污染。还避免了来自中心束的电子与偏转器112的区域中的能量滤波束相互作用所导致的电子 - 电子相互作用。

摘要： A soft ionization device is disclosed that comprises a series of electrodes (120, 122) having spacing less than the means free path of the molecules to be ionized. In some embodiments, the soft ionization device (99) is used in various applications that require ion or electron sources such as biological or chemical reactors, ion milling, and numerous replacements for conventional hot cathode systems. In another embodiment, a valence spectrometer is disclosed that is configured to variably ionize molecules (301) by their valiancy. In other embodiments, the ionization device is coupled to a spectrometer for the characterization of biological matter. Also disclosed is a preconditioner for preparing biological matter to be ionized.

摘要： An electron gun arrangement which is particularly suitable for use in travelling wave tubes includes a substantially cylindrical ceramic body (20) which partly defines a vacuum envelope. The body (20) surrounds an electrode assembly constituted by cathode (21), grids (22,23 and 24) and an anode (25). The leads to the grids and cathode are extensive in a generally longitudinal axial direction at the end of the body (20) remote from the anode (25), electrical connection being made via pins (30-33) and metallised apertures (26-29) extensive longitudinally through the wall of the body (20). The internal diameter of the body (20) may be stepped to define ridges (38-40) to which supports for parts of the electrode assembly are fixed.
