Commissioning & Characterization Of Magnetized Gridded Thermionic Electron Source, Mark Stefani
Commissioning & Characterization Of Magnetized Gridded Thermionic Electron Source, Mark Stefani
Electrical & Computer Engineering Theses & Dissertations
Collaborative efforts to design and fabricate a magnetized gridded thermionic electron source have been conducted between Xelera and Jefferson Lab. Commissioning and characterization of an electron gun fabricated by Xelera was performed to benchmark the viability of future electron source designs and capabilities. The work involved simulation, installation, trouble-shooting, modifications of the design, commissioning, characterization, and magnetization of the electron beam produced. A specially designed cavity as well as novel diagnostic tools and methods were developed, implemented, and experimentally tested. Finally, the gun was used to demonstrate a previously unachieved current of magnetized electron beam from a gridded thermionic source …
