Optical Emission Spectroscopy (OES) is a non-invasive diagnostic tool used to estimate plasma properties such as electron temperature and density via the use of collisional-radiative models. However, the estimation is prone to uncertainty due to intrinsic factors, and the measurement is non-local. Langmuir probes are used to measure electron temperature, plasma density and potential at different near-field locations. To measure the multiply charged ions and map the ion current density in the XPT, a Wien filter and a Faraday probe are used respectively. These diagnostics provide a comprehensive understanding of the plasma composition and propulsive performance, enabling design improvements and performance optimisation.
