The pursuit of novel technologies in the dynamic landscape of scientific exploration has driven the investigation of plasma lensing as a promising solution for optical matching at future positron sources. This research gains importance as emerging scientific objectives call for innovative approaches to advance experimental capabilities. Our initial experiments uncovered instabilities within the plasma and a significant level of copper sputtering at the electrodes. This presentation will explore these findings in detail and will also present the results of longevity tests conducted across various pressure regions and for two different materials.
