Electron beam technology is a unique technology that enables joining dissimilar and otherwise hard to weld metals with very precise and clean welds while minimizing the heating of the material outside the working area. In recent years, the use of this technology in additive manufacturing has become an exciting opportunity as this would reduce the operational cost of the technology and improve its versatility and performance. A current shortcoming of the technology is the short lifetime of conventional thermionic electron sources and their slow thermal response. In this project, you will investigate (experimentally and/or computationally) the use of a plasma cathode instead of thermionic emission as a source of electrons to overcome these limitations. As such, the project lays at the interphase of electrical engineering, particle physics, plasma diagnostics and scientific computing.
