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

文摘-III-9360073 PI：Owens提出了一种用于高能电子束焊接的新的电子源，它结构紧凑，但具有令人印象深刻的束流亮度和高能量。与传统的电子束焊机相比，这种新设备可以实现更小的光斑尺寸、更高的能量密度和更大的射程。使用特殊技术，在大气压下进行长距离焊接甚至是可能的。在该项目的第一阶段，将制造一个简单的电子束焊接装置并进行测试，以证明该概念的可行性。在二期工程期间，将建造一个高亮度、高能的设备。

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.
