COMMISSIONING & CHARACTERIZATION OF MAGNETIZED GRIDDED THERMIONIC ELECTRON SOURCE by Mark Stefani, PHD Candidate in the Department of Electrical & Computer Engineering at Old Dominion University
Abstract:
Collaborative efforts to design and fabricate a magnetized gridded thermionic electron source has been conducted between Xelera and Jefferson National Laboratory. Commissioning and characterization of the gun fabricated by Xelera was done to benchmark the viability of future electron source designs and capabilities. The work involved simulation, installation, troubleshooting, modifications of the design, commissioning, characterization, and magnetization of the electron beam produced. Finally, the gun was used to demonstrate a previously unachieved current of magnetized electron beam from a gridded thermioinc source of this uniquely compact size. This thesis addresses the following scientific and technological challenges: building a compact gridded thermioinc electron sources, production of high current magnetized electron beam, and demonstration of novel characterization measurements for magnetized beam.
