SPX.1 FZJ Tasks for 2023: VUV OES results H/H2 / Ne, Te and 2D distribution in JULE-PSI (FZJ) M. Reinhart, G. Sergienko, R. Rayaprolu, This work has been carried out within the framework of the EUROfusion Consortium, funded by the European Union via the Euratom Research and Training Programme (Grant Agreement No 101052200 EUROfusion).

VUV OES results H/H2 Seya-Namioka Vacuum Monochromator 500 mm focal length Typical resolution 0.05 nm with 1200 g/mm grating Status: - Under vacuum - UV light source added - Electron multiplier detector added To be done: - Setup of controls for the scanning motor - Setup for data aquisition
VUV OES results H/H2 Installation at PSI-2 at one of the top ports (Requires 90 mirror in vacuum) Top view of PSI-2: Langmuir probe Plasma dump Magnets Magnets Plasma source Linear Target manipulator
Ne, Te and 2D distribution in JULE-PSI Status: - First plasma in December 2022 - Langmuir Probe, Optical Emission Spectroscopy and Hyperspectral Camera measurements performed, also in comparison with PSI-2 - Results will be presented in Poster at PFMC 2023 Example: - Langmuir probe measurements of Neon Plasma electron density in JULE- PSI and PSI-2 - Peak electron density in same range - Difference in plasma shape clearly visible
Ne, Te and 2D distribution in JULE-PSI To be done: - - Complete analysis of results (Improvement of anode geometry/cooling for steady state operation) Vacuum vessel Magnets (actual inner diameter 13 cm) Aperture Andode Cathode Dump
Ne, Te and 2D distribution in JULE-PSI To be done: - - Complete analysis of results (Improvement of anode geometry/cooling for steady state operation) Thank you for your attention!
