A Compact High-Brightness Electron Source for Electron-Beam Welding

摘要-- III-9360073 PI：OWENS 提出了一种用于高能电子束焊接的新型电子源，该电子源结构简单，束流亮度高，能量大。 与传统的电子束焊机相比，新设备可以实现减小的光斑尺寸，增加的能量密度和增加的范围。 使用特殊技术，在大气压下长距离焊接甚至是可能的。 在该项目的第一阶段，将制造和测试一个简单的电子束焊接设备，以证明这一概念的可行性。 该项目的第二阶段将建造一个高亮度、高能量的装置。

ABSTRACT -- III-9360073 PI: OWENS A new electron source for high-energy electron beam welding is proposed which is simple, yet capable of impressive beam brightness and high energy in a compact structure. The new device can achieve reduced spot size, increased energy density, and increased range over conventional electron-beam welders. Using special techniques, welding at atmospheric pressures over long distances may even be possible. During the first phase of the project, a simple electron-beam welding device will be fabricated and tested to demonstrate the feasibility of the concept. A high-brightness, high-energy device will be constructed during Phase II of the project.
