    Abstract: A multi-beam electron gun provides a plurality N of cathode assemblies comprising a cathode, anode, and focus electrode, each cathode assembly having a local cathode axis and also a central cathode point defined by the intersection of the local cathode axis with the emitting surface of the cathode. Each cathode is arranged with its central point positioned in a plane orthogonal to a device central axis, with each cathode central point an equal distance from the device axis and with an included angle of 360/N between each cathode central point. The local axis of each cathode has a cathode divergence angle with respect to the central axis which is set such that the diverging magnetic field from a solenoidal coil is less than 5 degrees with respect to the projection of the local cathode axis onto a cathode reference plane formed by the device axis and the central cathode point, and the local axis of each cathode is also set such that the angle formed between the cathode reference plane and the local cathode axis results in minimum spiraling in the path of the electron beams in a homogenous magnetic field region of the solenoidal field generator.

    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: An electron gun also has a cathode for emitting electrons, a heater cap which contains a heater for applying the cathode with thermal energy for emitting electrons, a retainer for securing the cathode on the heater cap by clamping the peripheral edge of the cathode onto the heater cap, and a cylindrical Wehnelt supporter.
