Description
Liquid xenon (LXe) is predicted to sustain bulk electric fields approaching 1 MV/cm; however, experiments consistently observe dielectric breakdown at much lower field strengths, comparable to the operating fields ($\mathcal{O}$(10--100) kV) anticipated for the future XLZD detector.
The MOTION detector, an $\sim$70~kg LXe setup at the Karlsruhe Institute of Technology, is used to study dielectric breakdown in LXe. We investigate how local field enhancement at electrode asperities and stressed electrode areas affect breakdown using various diagnostic methods. This poster will highlight recent advances in electrode-surface scanning and the development of experimental instrumentation to support these studies.
