The Influence of Cathode Geometry on Plasma Characteristics in a Farnsworth-Hirsch Demonstration Fusor

This study examines the effects cathode size has on plasma characterization in a Farnsworth-Hirsch Demonstration Fusor. By comparing 3 different sizes of identically designed inner grids, the research analyzes factors like core shrinkage, ion leakage, and plasma stability.
