Abstract: One embodiment relates to a high-voltage electron gun including an insulator stand-off having a resistive layer. The resistive layer is at least on an interior surface of the insulator stand-off. A cathode holder is coupled to one end of the insulator 115 stand-off, and an anode is coupled to the other end. The resistive layer advantageously increases the surface breakdown field strength for the insulator stand-off and so enables a compact design for the high-voltage electron gun. Other embodiments, aspects and feature are also disclosed.

Abstract: One embodiment relates to a device that senses alignment and height of a work piece. The device may include both an alignment sensor and a height sensor. The alignment sensor generates a first illumination beam that illuminates an alignment mark on the work piece so as to create a first reflected beam, and determines the alignment of the work piece using the first reflected beam. The height sensor generates a second illumination beam that is directed to a surface of the work piece at an oblique angle so as to form a second illumination spot and images the second illumination spot to determine the height of the work piece. Other embodiments, aspects and features are also disclosed.
